Grenade
From benscondo.wiki-rpg.com
The M67 fragmentation grenade is the standard US military issue hand grenade since the end of the Vietnam war. In game terms, it can do up to 7d6 explosion damage (damage is applied to the wound track and not to any specific limb). Armor (SP) for the torso will apply to reduce damage, but if any body locations are unarmored, some damage will still apply.
In tactical combat, the grenade has an effective blast radius of 5 meters.
