This major milestone comes as the two countries commemorate the 10th anniversary of the Lancaster House treaty.

Ten years ago, the UK and France signed treaties at Lancaster House on defence and security, and on nuclear cooperation.

“This historic commitment has helped establish a long-term partnership and provides a framework for a joint response when mutual interests are at stake. One of the key goals of the treaties was to establish the Combined Joint Expeditionary Force (CJEF) combining two of the world’s strongest militaries to tackle shared threats.

The force has reached full operating capacity and can now rapidly deploy over 10,000 personnel in response to a crisis to fulfil a range of tasks including high intensity operations, peacekeeping, disaster relief or humanitarian assistance. As part of CJEF training, this week British and French paratroopers will come together for Exercise Wessex Storm on Salisbury Plain.

This sees soldiers from the French 2e Regiment Etranger de Parachutistes (2e REP) attached to the 2 PARA Battlegroup. Both units regularly train together to maintain their partnership so they are ready to deploy alongside each other.”

Defence Secretary Ben Wallace said:

“Today, the UK and France face a range of security threats of increasing scale and complexity. Having a highly capable, high readiness force is essential if we are to protect both UK security and the security of our NATO allies. It is testament to our close defence relationship that we have achieved all the milestones set out in the Lancaster House treaties 10 years ago, working together to protect our mutual interests.”

The UK and France are deployed around the world together in places such as the Middle East to combat Daesh and Estonia as part of NATO’s Enhanced Forward Presence, you can read more from the Ministry of Defence on this here.

  1. Nice idea in theory, but in practice I can’t see it ever being deployed. British and French foreign policies rarely seen to be aligned, mainly because the UK is focused on being part of the US and France wants to be independent.

      • I think Libyia was a bit of a wake up call to France and the UK at how poorly equipped they where to sustain any kind of campaign without US involvement even when it is on their back door.

      • Massively difference between what we are doing there under UN mandate and supporting France in a ground conflict.

        Libya was the same, neither country had any desire to get involved on the ground.

      • Desert Storm 1991, Afghanistan 2001-2015, Mali 2014-, Kosovo 1999, Lybia 2011, Syria 2011-…. I don’t know we seem to align fairly often….

      • In future, this will also mean the RM will have close ties with the newly formed German marines (Seebataillon) as these will fall under command of the Dutch marines.

    • The hilarity of that last statement. The UK just left the EU for the express purpose of maintaining its sovereignty, while France is focused on making the EU ever bigger.

      • EU is a trading block and has nothing to do with military alliances. From a military and political perspective we are fully aligned with the US and entered wars we really shouldn’t have because of that.

        Leaving EU and sovereignty is a joke. We voted positively (this is a matter of public record) on every law that passed in the EU and had veto for anything that we didn’t like. Large parts of our economy is based on cheap eastern european labour. We had full control over our sovereignty.

        • The EU is developing its own defence infrastructure, and numerous nations – including France – have been pushing for greater unification of European forces. To say the EU is just a trading bloc is understating it in the extreme.

          We quite demonstrably did not have full control over our sovereignty within the EU, otherwise we wouldn’t have had to leave in order to make the changes we wanted.

          Regardless of where we both stand on Brexit, the point still stands: the UK chose independence, France wants integration.

          • It was the UK which pushed for the European External Action Service (Common foreign policy and EU Diplomatic Corp) and the joint military procurement programs like PESCO, though we pushed against the ,multi-national military formations and the HQ (European Union Military Staff) for duplicating NATO.

        • Well Steve, that EU national veto is being curtailed in some areas and it will only be a matter of time before they move to majority voting.

          It’s inevitable, the EU has grown too big and without majority voting, they simply won’t get anything agreed.

          The main driver is for ever closer integration, if that’s what they want, good for them….

          Thank god we decoupled from that impending super state nightmare just in time.

          One thing’s for sure, it won’t be allowed again and you can bet your bottom dollar, article 50 will be put beyond reach for anyone else daring to leg it for the exit door from fortress Europe.

        • Did we have powers to keep ex-criminals out from freedom of movement, are you saying Blair could have vetoed this ? Perhaps his wife’s legal firms would not have done so well ?

  2. I’m sure there will be guys on here who know so I’ll ask the question…. Is this a ‘standing’ force ready to deploy at short notice and/or is it made up of other units, some ‘standing’ while others would be at longer notice.

    As has been said, I can’t see an anglo French force deploying on their own, its a good idea for interoperability etc but can’t see anything short of a Desert Storm where it would be used. I’ve been wrong plenty times before of course….

    • It’s been quiet and had very little mention for some time, but years back ( 96 or so ) the UK formed something called the JRDF, Joint Rapid Deployment Force, which was changed in time to the JRRF, Joint Rapid Reaction Force. I think I read it’s names changed again very recently, but at the moment don’t recall what.

      At its heart were 3 Cdo Bde and 16AA Bde, each which contributed a Commando Group and Para Bn Group at high readiness.

      CS and CSS Elements of both augmented these, along with outfits like 30 Signals Reg, our “out of area” strategic comms unit, the JHSU, RAFs TSW, Chinooks, Merlins from CHF, the usual RAF and Army logistics and movements elements, SF, and so on and so on.

      So yes, some is high readiness, others with longer notice to move.

      I’m not sure of its state of play now after A2020 Refine shuffled everything, especially with 3 Cdo and it’s demise, almost by stealth, from a deployable brigade to a golf bag of smaller units. 16AA is in better shape but still reduced.

      Many units are also by nature “duel hatted” in that they have many other commitments to defence.

      • I’ve just looked on wiki out of curiosity, and there is actually a pretty good article by wiki standards expanding more on my brief outline. There’s also a piece on it on TD Think Defence.

    • In reality, are the French and U.K. governments saying that their arm forces have spent the last 10 years regularly training together ensuring that they can effectively deploy together. However, each nation can only support a rapidly deployed force of 5000, so the maximum joint force would be 10,000 strong.

      Similarly, if we choose to train with another countries forces eg Canada, we could contribute 5000 troops to a joint rapid force with them also, but not at the same time we were deploying with France.

    • Depends on who is using it, but “standing” usually means a force that is a professional full time force, what in Britain is called the Regular Army. Within a “standing” force there are high readyness forces, and this is usually passed around a standing force because individuals get burned out being on high readyness.

      So in this instance the high readyness role will be being passed back and forth between 2 and 3 Para. When two para is on high readyness three para is recovering, and then switch. We did the same thing in 3 UK div but on a brigade level, some battalions/regiments to it on company/squadron level.

      I disagree with Bob that the UK could only deploy 5,000 personel maximum. We deployed that for Saif Sareea 3 a few years ago, and still where deploying battlegroups to Estonia, troops to Afghan, kept a high readyness brigade, and that before you touch the Paras and Marines.

      • Hi Dern,

        My post was rather rushed and could have been written with greater clarity.

        I did not mean to imply that the uk could only deploy a force of 5000. I just wanted some clarification on what the MOD statement was really saying when it referred to a combined force of up to 10,000.

        As both countries can probably deploy 10k troops each, why would a combined force be restricted to 10k max.

  3. Is it not in the interests of both countries to increase the resources which can be deployed quickly and perhaps independently of other NATO members. Sounds like a good idea to me. Perhaps we should look to build upon this.

  4. The UK and France may have identified 10,000 troops able to be deployed but where are the logistics, sea power, and air power to deploy them rapidly and sustain them for longer than 30 days without US support? They certainly can’t be sent to the Pacific. If we are talking Europe than NATO is involved. The French can’t even support the troops they have fighting terrorists in Africa.

    • I dont think its a problem for UK as the RAF is well equipped for it ,considering
      then french have to use RAF Chinooks in Mali it seems they are lesser equipped
      for it ,not sure if the US help is needed , you still on that high horse again pkcasimir?:)

      • The UK cannot sustain 10,000 troops beyond thirty days even if they use horses left over from WW1. That’s the truth, no matter how one sits on his horse .Try dealing with reality no visions of long lost glory.

    • The UK and France are two of the very few countries to have Blue Water Navies. Together we could indeed deploy anywhere in the world and sustain that deployment. The UK needs to upgrade our armed forces to be truly dangerous (the carriers need surface to air missiles for self defence for instance) but it is in no doubt that the capability is there if needed. It is however highly unlikely that France and the UK would be deploying to the Pacific without support from other countries as it is likely that any pacific issues would be in the interests of Malaysia, Japan, Australia, Singapore, New Zealand, US etc And so it is almost certain that they would be involved.

    • I think this is likely to be M Eastern/African deployment in which case either or even both of the countries have numerous and proven basing and supply line options. For APAC, yes you are right both countries would struggle beyond a short deployment. But I see no reason why either country would get involved in that, both countries are regional powers not world powers

    • That’s 2000 bodies to help the Liverpool council provide covid testing for everybody in the city.

      This is a trial, and if successful it will be rolled out nationally. If that happens, this might be the first French/uk joint deployment as we probably do not have enough uk troops to help test the whole uk population.

      • It is a trial.. it is also unlikely that everyone in the UK will be tested at the same time so those same 2000 plus a few more will simply move around the country. Also we would have to have many times that many deployed to run out of manpower as we have around 198,000 in the armed forces (although obviously some of them are deployed around the world already so would not be available).

        • Hi Lee,

          The plan is for uk to be able to test 2M people per day, which would enable everybody to be tested once a month. This testing will be managed by local councils so troops will need to be widely distributed if they are to assist.

          However, until we can test everybody, testing will need to be directed at areas with the most cases. Currently, 20%ish of England’s population are in the same tier as Liverpool, so to support similar testing in all these areas will need long term deployment of 25K bodies.

          I just hope the government can find alternatives to UK forces to do this role.

          • 25,000 are not going to be deployed to testing… Even if they are then that is partly what they are employed to do. Protecting the country means to both overseas and at home and they are there to be at the disposal of what the Government require them for. That could be rebuilding a burst dam, helping the police with law and order or helping the NHS with testing for Covid…

  5. It’s great we are working with the French but I do have a problem with this. Western nations have all sorts of ‘joint HQs’ – NATO, EU, bilateral, national. However the troops earmarked for each of these are the same people. This means once they are deployed through one HQs they can’t be through another. So the more chiefs than indians argument really does apply.

  6. Can I ask where the UK troops are coming from. It was only a week or so ago that we were told that we couldn’t put a decent brigade together for another ten years.

    • That article was referring to the future UK Division that was to be made up of 4 brigades, 2 AI, 2 Strike, as opposed to the current 3 AI. The army’s main war fighting division.

      I fully expect the brigades will revert to just 3 as previously and 1 armoured will be rerolled. In fact, a Lt Gen has already indicated that we will move to a “square” brigade.

      That implies 2 tank, 2 Warrior. At the moment they are triangular, 1 Tank, 2 Warrior.

      These troops are drawn from other areas of the forces which I outlined earlier.

      • Has 3 Div actually converted to it’s triangular brigade Orbats yet? I haven’t heard of the 2nd Strike Brigade has been stood up yet, or if it’s just the Strike Experimentation Group. If that’s the case the 2 AI brigades probably are still consist of 5 Regiments/Battalions.

        • Evening Dern. Unsure. I always describe the planned end states as per the latest reviews, which as we know change before the previous has even taken full effect!

          As far as I was aware the 3 AI still had their 2 warrior 1 Mastiff, 1 Tank. I’m not even sure if KRH has converted to Armd Cav yet.

  7. Yes we can deploy together, be it 1000 or 10000 strong. The key here is for how long and with what effects? For warfighting and long term operational tasks we have to be realistic and understand that we are lacking key enabling assests, logistics and supporting arms for any meaningful intervention. Yes we have amazing people, some top of the range kit and certain capabilites that few others possess in numbers or of a decent standard (RFA, SF, ISTAR, AAR, heavy lift rotary, heavy lift aircraft to name but a few) But as an organisation, we lack a coherant defence strategy, we lack depth and the ability to take losses (operational or mechanical) and we seem to lack the will in the MOD to sort it out. We rob Peter to pay Paul when it comes to deployments and our current ability to go toe to toe with an opponent, and come out top, is in my mind in doubt. many of us have said this before but shiny kit doesnt win wars, but the skill, knowledge and ability to use it to its best effect. Anyway moan over, as for the French, worked with them lots of times, and contary to what many may think, good lads, up for a bit of a ruck, and as a country France has been willing to deploy and use what they have to its best effect. Good allies to have, despite the political claptrap that goes on. Cheers all, stay safe.

    • By more luck than judgement the uk hold most of the cards when it comes to fishing in the north sea.

      When we joined the eec/eu fishing rights in the North Sea 12 miles from the coast were an unregulated free for all. The introduction of the EEZs in the 1980s changed this as the North Sea was split up between the countries that surround it.

      What allows us to have all the cards is the biology of the North Sea. Young fish hatch and spend the early life in the shallow waters in the south of the North Sea ie France, Belgium, Holland and Denmark, but then migrate to the deeper waters further north to grow into adults. This is predominantly UK waters, so viable fishing can really only occur in uk territory.

      • The issue may arise though with agreements we made prior to joining the EU. For instance Belgium have and agreement with the UK that they have access to our waters, The norther European states also have had historic agreements to fish our waters. That makes legal arguments a little tricky. For instance if we disregard our treaty with Belgium then that makes our treaty that gives us Gibraltar very shaky…

        • You are right Lee.

          The agreements we signed before joining the EU may only relate to the waters up to 12miles off shore as these were written prior to the formation of the EEZs.

          The Belgium agreements may have been super rested by more recent Eu wide laws.

          We will just have to see I guess.

        • Agreement with Belgium? If you mean a Royal concession by Charles II – I’d expect either Parliament or the Crown could revoke it. As for Spain – if they repudiated the Gib Treaty I’d expect the UK would simply ignore it.

          • Spain is never going to give up their Ceuta or Melilla enclaves in Morocco, so they’ve not a leg to stand on disputing Gibraltar.

            However our fishing fleets & industry has been decimated through EU membership.

          • Lets not forget that fishing fleets were on the decline before we joined the EU and that during that time the northern European countries along with Belgium had full access to our waters anyway and had done for centuries… Also our fishing industry is negligible in relation to GDP. There are far more important industries to look after with regard to trade agreements.

            And yes Spain do have a leg to stand on with regard to Gibraltar if we start to disregard treaties that we handed out.

          • And that is not a good look for a country that likes to take pride in it law and order and its honesty on the international stage. If we expects treaties to be honoured in our favour then we should expect to hold our own treaties in similar regard.

  8. If the UK has to rely on French support we really are in trouble. Usually its the reverse. Look at how much support France and Germany gave UK during the Stena affair ( which really occurred because the US wanted the EU to uphold its own sanctions – didn’t happen of course).

  9. Hard to see a situation where such a relatively large Anglo-French force would be deployed outside of a broader NATO operation.

    • Agree. But you never know in war. That we have the capability and a militarily effective ally is a good thing.

    • I can see it given a set of circumstances. Trump staying in power and not wishing to intervene in any kind of N Africa operation (let’s say Libya based Jihadi group starts sustained euro terrorism campaign.) Britain and France would be the natural leaders in intervention, backed up by other european/EU countries supporting them. This is the likely scenario which will weaken NATO – perhaps fatally and encourage the development of EU army/armed forces
