From their announcement:
Micro Melee is a rules system for recreating company level engagements of WWII in 6–15mm. Although it would be a stretch to manage a battalion level game, it could be done, provided there is a large space with multiple GMs. Micro Melee handles movement, identification, combat and leadership from the perspective of a platoon. Command is assigned to Lieutenants, Captains, Majors and Colonels within HQ units. Much of the detail for individual soldiers is incorporated abstractly.
