Wonder if a dedicated sniper would work if they gave a pet multiple copies of the same 'snipe' power but with different names. Probably just look like snipe1, snipe2, snipe3, but have the exact same stats. Just so he could continue shooting. Would require more intelligent placement I guess.
Grenadier would just get the M30, Teargas, Flashbang, Toxic Web, and I guess whatever other grenade type powers there are.
Figure theyd replace the generic t2 guys.
