Don't think that any of the changes for pathfinder would work, or we would have to change it for all axis infs too (JLI etc)
The thing is that JLI are CP 1 that make it more difficult to spam.
Generally speaking I would try making some of these units have cloak as an ability with cd instead of a passive and that includes ostheer doctrinal camo.
(one could even expand that to moving camo part for units like commandos/ST/Partisan in order to require more decision making on the part of the player when trying to navigate the battlefield)
The XP is at pioneer level which is simply too low.
As for the elite carbines (not the scoped one)is has profile that is simply bad for the unit. It does not work well with the scoped ones since it has low far DPS while allow the unit to fight even when rushed because it has great close DPS.
You talk about the vet 1 smoke or?
I am talking about "Concealing Smoke" ability the unit has a very long range and does not really have a reason to get defensive smoke since it add to already 3 shots durability.
