The general feedback is lukewarm, whilst they recognise the reasons for their creation these forces will only work in expeditionary role. Can you imagine UK throwing Ranger Regiment in Kremlins path - it will be a blood bath.
We recently announced an upgrade to Challenger 2 tanks but I now expect the numbers to be increased as well. I would also like to think that the number of regular army will be increased rapidly and UK will likely try to permanently base some units in Latvia. They might reactivate their German bases which were let go of recently but that might not happen - I am not certain what leverage UK has anymore over Germany to get these bases back. Most likely number of F35s will increase and if that is becoming too costly Tempest will be accelerated to make the numbers up.
The Navy is doing fine for now but I would expect an increase in the number of Royal Marines to about 30K fighting force with 10K Reserve.
