There are many ways to enjoy Army Men. The simplest and most common involves a sandpile or dirt backyard, small garden trowel and wood twigs. You can dig bunkers, fortifications and trenchlines.
Soldiers ride in hoppers and gondolas.
Do not stuff them in boxcars because it is hard to get them out. Note that a train can crash a tank, but a tank cannot crash a locomotive. Outdoors, soldiers can be bombed with 'enemy dirt bombs. Small, dry clumps of dirt will seem to explode upon impact. The cheap spring-loaded firing cannons sold with Army Men don't pack much punch.
