There are currently no Units making employ of the Slammers cargo space. Tactics would be heavily focused on making use of this feature where possible, since direct infantry support for tanks makes them much more effective in any kind of combat.
The Units should have the following compositions:
Heavy Infantry Armor Squad:
Lead Tank (1x Slammer, 6 Infantry in cargo)
Team leader, LMG Gunner, LMG Assistant, Grenadier, AT Gunner, AT Assistant
Second Tank (1x Slammer, 6 Infantry in cargo)
Team leader, LMG Gunner, LMG Assistant, Repair Specialist, Squad Medic, Rifleman
And should as well be available as an individual tank + Infantry team as follows:
1x Slammer, 6 Infantry in cargo
Team leader, LMG Gunner, LMG Assistant, Repair specialist, AT Gunner, AT Assistant
