I see this little guy being a good base defender and it would be the only plane in the game dropping smoke. Most importantly, it adds another country's plane.
"No. 4 Squadron and No. 5 Squadron flew Boomerangs in New Guinea, the Solomon Islands and Borneo in the close support role with marked success. Tasks included bombing, strafing, close infantry support and artillery spotting. When attacking larger enemy formations Boomerangs often operated in conjunction with heavier aircraft. In this role the Boomerang would get in close to confirm the identity of the target and mark it with a 20 lb (9 kg) smoke bomb with the heavier aircraft delivering the major ordnance from a safer distance. The partnership between 4 and 5 Squadron Boomerangs and RNZAF Corsair fighter-bombers was said to be particularly effective."
"With good range, heavy armament, and excellent low-level handling characteristics, the aircraft could avoid ground fire in even rough terrain and still inflict heavy damage. The extensive armour plating protected the pilot, the aircraft\'s simple wood and aluminum airframe capable of absorbing a great deal of battle damage, the ability to drop target-marking smoke bombs for other attack forces, plus two cannons and four machine guns, made for a very effective low-level combat aircraft. Flying in pairs, Boomerang tasks included bombing, strafing, close infantry support and artillery spotting "
Look at it this way!
