The command structure of a team consists of the basic entity command.
Command Structure Overview
There is basically 3 types of commands, Assault Team, Strategic Command and the Supreme Command. The 3 operate on different levels within the command structure.
Supreme Command
The Supreme Command is the top-node of a team. It is not controlled by a single player like the strategic commands but rather by the highest commanding players (via their strategic commands). Everything comes from here (captured factories are assigned to supreme command, which then re-assigns control to sub-commands) and everything falls back to this command. The Supreme Commander can also move the team's capital if needed.
Strategic Command
The Strategic Command is everything inbetween the Supreme Command and the assault teams. Strategic Command makes the overall strategic decisions, handles the logistics of getting men and tanks to the frontlines, setting up defences in areas that are under threat and the management of war factories.
Tactical Command
Simply put, the Assault Team is a the bottom of the army structure, directly engaging the enemy in tactical situations. Only an assault team can initiate a direct attack, higher commands coordinate larger operations by issuing orders in order to to the assault teams.
