[SG] Stargrunt WW2

Beth,

Rifle grenades (those you fit on the end of a WW2 rifle) did exist, but I
suspect their use was... somewhat rare. If you want to represent them, 1 extra
FP might be okay (I think it is an
under-rating for modern grenades from
underbarrel GLs, and an utter ripoff for 2183 grenades, but that's only
because whenever you play with them in a skirmish game, they
have a _huge_ impact, and in the GZG world, it
seems EVERY figure has one).

Hand grenades are subsumed in modern terms in the Close Assault rules, and
that is where they live in WW2 also.
