The He111 operated in every front the Germans fought but it's probably best remembered as the Luftwaffe's main bomber in the Battle of Britain. That battle showed up its weakness in defensive armament. The H model was constantly improved during WW2, starting with more defensive guns. It was also used as a torpedo bomber, paratrooper transport, cargo carrier, glider tug. Later bombers had a dorsal turret instead of the ring mount, bigger bombloads, some were even used to launch V-1's. The most impressive was the He111Z (Zwilling), which was made using two He111's, joined by a central wing section, with a fifth engine. This was for towing the huge Me323 glider transport.
ICM are a Ukrainian company who have recently seen a huge improvement in the quality of their kits. The He111 kits are high quality plastic kits with good detail and generally excellent fit of parts and are highly recommended kits. Each kit comes with decals for one Romanian aircraft. Note with aftermarket decals, this could easily be made into a Luftwaffe aircraft.
