After posting I got to thinking and I don't want to retcon things though, so I guess what I'll do is say at some point the Humvee was damaged and while at the depot had the glass that I was originally thinking of installed, but only for the front (since it the door glass hasn't been relevant as of yet).
Thanks a lot, appreciate it. I'll have to get that issue of Osprey too.

Here's a video of Mr. Guns & Gear shooting a Hummer window with 5 rounds of 7.62mmR ammo. NO PENETRATION.

This is a video from Texas Armoring showing a car with NIJ Level 4 windows being shot at by an AKM.

These videos prove that the Hummer's windows are at least NIJ Level 3 (rifle) and more likely NIJ Level 4 (rifle) in construction.
In my game, the AV's are
NIJ Level 1 = 1/4 AV [multiplied by Pen]
NIJ Level 2/2A = 1/2 AV [multiplied by Pen]
NIJ Level 3A = 1 AV [multiplied by Pen]
NIJ Level 3(Rifle)/SAPI Plate = 2 AV [multiplied by Pen]
NIJ Level 3+(Rifle) = 3 AV [multiplied by Pen]
NIJ Level 4(Rifle)/ESAPI Plate = 4 AV [multiplied by Pen]
BUT I also now do Penetration based on the round's VELOCITY modified by its SECTIONAL DENSITY (unlike GDW's original formula). My Penetration Numbers are:
4,000fps+ of velocity = 1/2 Pen
3,000fps to 3,999fps of velocity = 1 Pen
2,000fps to 2,999fps of velocity = 2 Pen
1,000fps to 1,999fps of velocity = 3 Pen
999fps or less of velocity = 4 Pen
Here's an old video from the Wound Channel showing a 55gr M193 ball round punching through an NIJ Level 3(Rifle) plate because it broke the 3k velocity threshold. The same round will bounce off of this type of plate once the velocity drops to below 3k fps in speed.
