From the manufacturer:
During the final days of World War II, Allied troops crossed the Rhine in order to complete their invasion of western Germany. The Allies took control of the last remaining Rhine bridge, Remagen, on March 7, 1945. Of course, the Allies' success was made possible by the M4A3E8 Sherman and M24 Chaffee. This limited edition kit combo features four 1/72 tank kits: 1. Tiger I, 2. Panther G, 3. M4A3E8 Sherman and 4. M24 Chaffee, each with markings representing each tank as it appeared in Western Europe, circa March 1945.
Parts come molded in gray. Includes decals.
