Did the m18 hellcat serve in D-Day?

No, the M18 Hellcat did not serve in D-Day. The M18 Hellcat, a tank destroyer used by the U.S. Army, was introduced later in World War II, with production starting in 1943. By the time of the D-Day invasion on June 6, 1944, the Hellcat was not yet in service in Europe. The vehicle saw extensive action in the latter part of the war, particularly during the Battle of the Bulge and in the push into Germany.
