The misinformation and theory crafting in this thread is disgusting.
Veterancy awarded and squad value follow the same formula for 90% of the squads in the game. Dividing the manpower cost of the squad by the number of models and acting like this is a useful metric is moronic.
XP awarded for damaging/killing an entity is related to cost of entity itself and not the actual squad value. So one has to divide the squad value by the number of entities. Thus the argument that axis vet faster for attacking more expensive squads hold little water, if their is advantage allied infantry have it for firing on more expensive entities.
I do agree that it WFA that need to be toned to EFA level and not the other way round.
