soldiers do many things, from shooting enemies, to digging defensive trenches. they are used to defend their country, or attack another country's army. it is difficult, and soldiers must be in good shape, both physically and mentally. they almost always move together, and that way the team can do more things, in a safer way. they may be assigned to certain places to guard, or they may be told to search a place, or even attack it. that is up to their commander. every soldier answers to someone else, so that way, everything is organized.
