In 1943, he enlisted in the Army, and because of his intelligence, he
was assigned to a specialized counterintelligence unit, the 603rd
Camouflage Battalion. Its mission was to fool the enemy by
impersonating other Allied troops in battle, and he spent much of his
war inflating rubber tanks that served as decoys. He landed in France
about a month after D-Day, and participated in 21 engagements,
including the Battle of the Bulge and the crossing of the Rhine.
