The psi-operative has an ability called Fuse which can prematurely detonate an enemy's explosives. As you can imagine this makes my inner child giggle with evil glee. However, it would help to know some further details.
WHICH enemies carry explosives for targeting?
Do those enemies have a chance to be equipped with an explosive, or do they always carry them?
Can they carry more than one explosive, and if so, do they all cook off at once, or do they have to be Fused one by one? (Even if this isn't relevant to enemies in singleplayer, I'm almost certain it will be in multiplayer with grenadiers)
