Maybe. You'd be amazed at the .50-cal onslaughts I saw unleashed on dinky little cars, yet it didn't stop them. Crazy stuff.
I have absolutely no experience with any machine gun tho I once had a Beretta .22 short go full auto by accident. It fired three shots in a burst so short that I had to count the ones left in the mag to know how many actually fired.
I do remember a long video from I have no idea where. It was of the lead tank in the advance on Baghdad. A guy was manning a .50 and was half way out of the turret.
As they moved along, he blasted several vehicles and stopped them cold. I can still recall him firing just a few rounds at a pickup truck. After stopping he would for some reason have to work the action again to prepare for the next target (victim).
The tank never used any other weapon but that .50 just kept knocking everything out.
