His award citation reads:
The President of the United States of America takes pleasure in presenting the Navy Cross to Private First Class John M. Gross (MCSN: 356609), United States Marine Corps (Reserve), for extraordinary heroism and devotion to duty while serving as a Radio Operator for the Assault Regimental Commander of the Second Marines, SECOND Marine Division, during action against enemy Japanese forces at Betio Island, Tarawa Atoll, Gilbert Islands, on 20 and 21 November 1943. When a scant foothold had been gained on the beach and the Regimental Command Post temporarily established under the Betio Pier in the face of heavy, persistent enemy fire, Private First Class Gross skillfully installed and operated his vital radio equipment as the only means of communication available to the Landing Force Commander and, courageously refusing to take cover from the intense Japanese machine-gun and sniper fire which hit all around him and destroyed one radio antennae, steadfastly remained at his post throughout the critical stages of the Tarawa Operation. Private First Class Gross' expert technical ability, great personal valor and tenacious devotion to duty under extremely perilous conditions were in keeping with the highest traditions of the United States Naval Service.
Gross was born in Algoma, Wisconsin. His home of record was Racine, Wisconsin.[1]
