From the update:
M10 Tank Destroyer Platoon (UBX31)
The M10 3” GMC (gun motor carriage) tank destroyer was developed to handle medium and heavy German tanks. It was the first destroyer to incorporate a turret, which housed the 3” anti-tank gun, the best in the US arsenal at the time.
Each box includes four M10 Tank Destroyers (with optional Duckbills & Top Armour upgrades) with crew and plastic parts sprue, two Tank Destroyer Stowage sprues, one Decal sheet & eight Rare-earth magnets.
