The new Caesar Miniatures US Army WWII set 1 in soft plastic 1/72nd scale contains two very common weapons, frequently seen in the hands of miniature soldiers. The flamethrower and the hand grenade.
In my wargaming rules I give each of these weapons a range of 50 meters, that's five inches in real world scale. Since infantry can run ten inches, that is a pretty short distance. One of the main advantages of these weapons is the ability to attack a bunker. Get the figure right up next to the firing aperture; easier said than done. Then roll a 1 on a D6 for the hit location. If you score a hit, the bunker is burned out or has a grenade explode inside it.
