If you got into the arsenal and that's a big if, the gun's are marked with the calibre and the ammo is marked too so no probs there , stripping and cleaning would be a bigger problem but once in there will be tool's manual's and consumables the armourer will use lying about, as for grenades they will be unprimed/unset and the detonator cap will be more than likely stored elsewhere in the armoury....grenades are not a trial and error piece of kit!!!
Nothing is fool proof for a sufficiently talented fool!!!!
