National interest and intent will dictate future Brigade set-up. The UK & France are gearing themselves towards maintaining an expeditionary capability. The UK being an island nation with a greatly reduced European military presence (BAOR disappearing), it makes complete sense.
The UK plan to have five multi-role brigades (mech infantry, SPA, MLRS, armour, light and medium forces) + two rapid intervention brigades 3 - Commando and 16AA. This will allow the UK to 'independently' deploy and maintain at least one brigade on active service indefinitely (Afghanistan for example) and still have the 'fat' to undertake a shorter term operation (strategic raiding). All done with continued NATO participation in mind. The French are looking at a similar concept maintaining the ability to operate independently to protect national interest, but also have the resources to work with other European partners by sharing resources with others (in-flight refueling, strategic lift and possibly RFA's).
Other nations may decide to focus more of self-defense and peace keeping operations and invest more in land based systems rather than expeditionary - Germany comes to mind as they don't have a strong amphib fleet.
Flexibility is the name of the game, being able to work with partners but also retaining a limited ability to act independently. Shrinking budgets mean that the days of keeping a division on active service for extended periods has now been reduced to keeping a brigade on active service for extended periods for many in Europe. In a nutshell a brigade will be formatted for role as determined by a country's strategic interests.
You do have a great point here, as national budgets decline and keep declining.
For example the Dutch their army use to be rather strong and very well equipped,
However due massive budget cuts their army switched to fully proffesional and task based roles such as peacekeeping.
We see this with other EU based nations to.
None of them are expecting to fight a large battle or a long lasting high violence war.
Thats does not mean they are not capable to do so as the general idea is that if a major war in the future happens that other nations like US, UK, France, Germany, Italy and Turkey (To name the 6 big ones) take on the "heavier" stuff.
However would that not bring a united EU army or some sort of EU national army into affect?
Because in the past there have been talks and ideas about a unified EU army, which would give the EU a very capable and credible army and strenght, where the smaller nations like Dutch, Belguim, Danmark and so on can full fill their smaller but perhaps more specialised tasks?
I mean like you said: The UK & France are gearing themselves towards maintaining an expeditionary capability.
But does this not hurt the overall capability of the EU as a allied system?
Where you do draw a line between, Cuts, Reforms, and tasking before a nation becomes to dependant on allies? before it loses the ability to protect their intrests at all?
Because having the major nations within the EU reforming their army at the scale it happens nowadays (Due budget cuts and a increasingly changing world) would that not hurt the EU/NATO in general as each nations is about to shrink to a point where global security and peacekeeping/fast intervention tactic starts to hurt national intrest and international intrests?Also NONE of the nations will be able to maintain such intrests if a future enemy is able to escalete i believe.
Specially with mosty nations disbanding and scapping some of their key roles, like the dutch did with their Leopard 2 fleet and their navy and airforces.
So imo you are starting to see nations with armies that are tasked with a few roles, but none of them are able to sustain a major campaingn, however putting all those nations under one command (For example during a serious war) would enable them to combine the "knowlegd and nation based skills and strategic options"
I am not sure if you follow what i am saying but basicly the average army in the EU has in some cases being cut in 50% or even more in some cases.
So where does the EU nations draw a line where a brigade does not be able anymore to operate on its own to life up to those intrests and protect them without the major help of an ally?
