I've been playing probably pretty much non-stop since Saturday afternoon. Your troops do fatigue, they fatigue faster going up hills trudging through snow etc. The difference is, as in the real world. When you are at the top of your game, you know a cornflake-eating-out-of-someone-elses-hollowed-out-skull-Germanic-barbarian-warrior-studmuffin. You have a quick recovery time. So while you may be breathing hard by the time you get into position, it will only take a short breather untill you're "warmed up" again.
