These are the five options for machine gun templates that we use. They can actually be pared down to two, the two three-leaf ones can be done in clear plastic with the outline of a single or double leaf drawn on them. Then you can use the one three-leaf template as a stand in for all three. I like this myself.
Five WWII Revell Russian Infantrymen on a single template. Troops packed close together can really be devastated by automatic weapons fire. I use the single template for all magazine fed automatic weapons, BAR, Bren, Thompson, etc.
A single tripod mounted machine gun takes out a whole Russian squad in one burst. Attacking across open ground against even a single machine gun is a very poor tactic.
