It would be like carrying chargers for phones you don't have. Only way heavier.

Sgt. Rock was traditionally drawn with two .50 caliber machine gun belts over his shoulders, even though he didn't carry a .50 cal. He usually used a Thompson which would've been .45, not the .30 he mentions here! Well, everyone can have an off day. From 1977, Sgt. Rock #308, "One Short Step--" Written by Bob Kanigher, pencils by Lee Elias, inks by Romeo Tanghal.

Holding off Easy Company's retreat, Rock is captured when he runs out of ammo, and is taken to an old Roman arena outside a French town. The Germans are honoring "Hans Krug…the perfect German Soldier!" and to rub it in the noses of the local French, they decide to hold a little contest with Rock. Rock comes in second-best in the marksmanship and bayonet drills, but manages to knock Krug out in hand-to-hand, inspiring the French to throw down and cover Rock's escape.

Krug goes after Rock, chasing him into a cave filled with human bones, stone weapons, and paintings. Rock finishes Krug off with a flint knife, musing that people haven't changed since the stone age. You may have noticed, even captured, Rock still had his .50 cal belts!
