I guy I know who saw action in several military campaigns once told me that Belgium (surprisingly!) has the best soldiers of all the NATO countries. What he found most impressive about their soldiers was that they had very little "specialization" among them, and they were all trained to deal with almost any situation that came up in the field: infantry operations, sniper ops, fixing a Humvee that broke down in a convoy, translating in X different languages, etc. It seemed like they never had to call someone else to a situation to deal with something that was beyond their capabilities on the spot.
For whatever that's worth ...
