From the announcements:
The US army have taken bunker clearing to a whole new level with the new US Flamethrower Team!
Flamethrowers were used throughout the war, especially in the Pacific, to clear our tunnels and bunkers. During the Normandy landings the number of flamethrowers was increased to allow the men to open a gap in the fortified Germans lines.
Warlord Games’ British Airborne are ideal for fighting in North West Europe where they could be used to re-fight actions such as the assault on the Merville battery, the coup de main attack on Pegasus Bridge, the heroic battles of Operation Market garden or onward to the crossing of the Rhine and Operation Varsity.
