Any particular reason for a bullet-proof windshield, 411A?
Perhaps a pigeon with an AK..
I think I'd rather take my chances with 5 AK-47 rounds fired at my 767 windshield from 350 yards than take 5 birds hitting it at 350 kts.
One of our 767's hit a flock of some type that weren't too big >10K near 350 kts. It looked like multiple 20MM cannon hits. One poor bird went just under the windshield, through the pressure vessel, through the side cockpit walls and splatterd guts into the Captains kitbag.
