Flames of War got some new armor in their line with the release of the M4A3 Sherman Platoon.
From the update:
The M4A3 (76mm) married the new M4A3 hull with the 76mm gun, making for a fast, hard-hitting tank. This gave US tank crews a definite edge over German medium tanks, as well as giving Panther and Tiger crews something to truly fear.
Each box includes five M4A3 (76mm) Sherman tanks, one Tank Commander sprue, two Tank Stowage sprues, five Plastic Sherman accessory sprues, one Decal sheet & ten Rare-earth magnets.
