other than that?
crotch guards?
Depends on the environment you're in. Australia is well sorted for working in hot climates, but less well so for cold environments (given the fact that we barely have any)...
Most Australian troops wear their own thermal shirts and underwear when they have to operate in cold climates, the issue jumpers etc are pretty ordinary.
In relation to body armour, some heavier types of body armour do have "crotch guards", newer types also provide protection around the neck and sides of the shoulders.
