Bt the start of a simulation, the Combat Simulation Module (CSM) randomly picks
the initial location of all cybertanks. Cybertanks can only be placed on grass,
roads, dirt patches, etc. That is, they can only be placed in non-obstructed areas
of the battlefield.
The Battlefield Design Module (BDM) lets employees create their own battlefields
for combat simulations. There are few limitations in battlefield design, but there
MUST be at least 30 non-obstructed areas (to allow placement of cybertanks) included
in a design. If there are less than 30 the Illegal Battlefield error is displayed
when YOU attempt to save the terrain.
