types of terrain feaures. Military symbols have been devel-
oped to represent various types of military organizations,
activities, and installations. FMVI 21-30 lists various standard-
ized military symbols. Figure 4 shows some of those most fre-
quently used. These symbols are used to indicate size and
identity of various units and installations, type and location
of supporting weapons, and necessary lines and boundaries
for an operation. A material saving of time in giving orders
for military operations may be achieved by using military
symbols to outline operations on a map or a mrnap substitute.
