The reduction in length by 15 inches (38 centimetres) did not reduce performance; penetration was the same as the 3 inch gun. By August 17, the Ordnance Department had classified the test gun with the shorter barrel as the 76-mm M1 and set up the precedent for the designation of M4 tanks armed with the gun to include "(76M1)".Type: Tank gun.

Penetration resistance test is conducted on concrete structures using Windsor Probe test machine. In this test method, a steel probe is fired on the concrete surface by a sudden explosion. The penetration is inversely proportional to the strength of concrete. The result of the test is influenced by.

This penetration fractures the concrete obstacle from within, breaking it into smaller blocks, which can be cleared with an M9 Armored Combat Earthmover (ACE). A concrete block 6 feet in diameter and 6 feet long is broken up into rubble, which can be cleared by a tank equipped with a bulldozer blade.
