Breaking glass is an exaggeration. It is certain that sonic booms can shatter glass. However, a sniper rifle loaded with a.50 BMG bullet can't break the glass even if it is close to it. A foreign team once did an experiment, using a.50 BMG AR50 sniper rifle to make the bullet only a few centimeters away from the glass, so it was impossible to break the glass. When the F 18 Hornet fighter flies at a low altitude of 60 meters at supersonic speed (it is said that this is the lowest altitude allowed by legal flight), the glass can't be broken. But how strong is the armor-piercing ability of M82A 1? First of all, different bullets have different effects. And distance plays a very important role.

Using M8 armor-piercing incendiary bomb, the steel plate with a thickness of 20mm can penetrate 100m, 500m 16mm, 1200m and 8mm.

The Mk2 1 1 Mod 0 API armor-piercing incendiary bomb can produce 20 fragments when hitting a 2mm thick steel plate, which can effectively deal with light armored targets (1000m can penetrate at a 45 angle 1 1mm thick steel plate).

M903 slaps the armor-piercing projectile,

At 500 meters, it can penetrate 34 mm thick hardened armored steel plate; At 1200m, the hardened armored steel plate with a thickness of 23mm can be penetrated. Hardened armored steel plate with thickness of 19mm can penetrate within the distance of 1500m; However, Mk2 1 1 can only penetrate the steel plate with the thickness of 1 1mm in the range of 1000m, and the difference in power can be seen.

Therefore, using M82A 1 can't deal with active main battle tanks even at close range.
