For all intents and purposes the glider troops were equipped just like normal infantry during the Normandy campaign. The M1942 jump uniform was limited only to the parachute troops, as were the classic Corcoran jump boots. The parachute troopers (who were volunteers) also got extra pay that the glider troops )who were NOT volunteers) didn't get (although late in the war the glider riders did get hazardous duty pay).
After the Normandy campaign, as the airborne divisions reequipped before Market-Garden, the troopers all received M1943 uniforms. The parachutists added the big thigh pockets that they were used to. I'm not sure if the glider troops added the pockets also, but at least some did. All the troops were supposed to have the M1943 "double buckle" combat boot, but the parachutists objected strongly and were able to keep their jump boots.
So Andy is quite correct in showing these guys in "regular" infantry uniforms and equipment. The helmet net with hessian strips was usually associated with the airborne troops in the Normandy campaign. They apparently got that from the British airborne.
