We have it here in Sweden sort of. Nowdays only 7-8 thousand make it in each year though. It's a fairly good system for us since we aren't forced to go to an actual warzone. Most guys in my age that are fit and like being outdoors fight for the spots. It's actually a good experience according to my brothers. You learn self-discipline, teamwork etc. and you actually don't learn that much about combat except with assualt rifles. Two years sounds too much though, our longest traning for officers is one and a half year. In short it works rather well for us and i think it might work for you too.
