The way Panzer Command is designed, it basically puts you in the role of the Company Commander. The orders system is designed to represent what you could reasonably communicate to each platoon commander during a turn and your orders are based around the platoon as the base unit for orders. You can also give orders to each individual tank or squad, within the limits of the base order for that platoon, but issuing orders by platoon with some tweaks down to the tank or squad level is encouraged and also helps things move along fairly quickly.
As a result, there's no formal command structure, but the model of command is built into the game design itself. Platoons do have their own structure though and many things are resolved at the platoon level - we track the platoon commander, platoon morale, platoon orders, etc. There are plans for the future releases in the series to go up to the battalion level and add an additional company command layer with a more defined structure, but that's still just a plan at this point.
