Bullet proof glass?

Ran across this picture over at yahoo news...

http://news.yahoo.com/photo/050921/481/sao20209212110/print;_ylt=AvxVJeM...

Maybe its just me, but demoing with a "38 caliber" (presumably a 38 special) seems a little underwhelming....

Anybody know what typical bullet proof glass is rated at? This site claims glass rated up to 7.62x39, 308 win (7.62x51 nato), and 223 rem (5.56x45 nato).

It even mentioned 50 cal. I'm not sure I want to be on the inside when the 50 cal started pounding my vehicle. sad

In my experience most bullet proof glass is typically rated up to 7.62. At least that's generally been the standard with security applications I've been involved with. I'm sure there's variants rated higher or lower, but 7.62 is probably the most common.

Interesting, for some reason I thought it would hold up against more powerful rounds.. Thanks for the info.

The one way glass is good up to 7.62 NATO but the conventional glass has a rating up to .50 cal.

Quote:
Protection levels range from Type IIA up to beyond Type IV as per the NIJ Standard, including NATO calibers. The products for higher threat levels includes protection against 7.62x39 Armor Piercing Ammunition, 7.62x51 Armor Piercing Ammunition, 5.56x45 Armor Piercing Ammunition, 12.7mm (50 caliber) machinegun rounds, and side bomb blast. Depending on the makes and protection levels, there are spall and no-spall armor glass and scratch resistance for the plastic is optional.

This is some bad arse glass! Yes

Given the energy behind a .50, I can't imagine how thick the stuff would be -- or how expensive. I've ridden in up-armored SUVs in the ME, and they're pretty hefty. They said the safest place to be in the event of rocket attack was in the vehicle, but it's tough to get past the notion that the vehicle may be the target. One thing that hasn't changed since the Taliban caved is that leadership still drives white SUVs -- they're just newer vehicles because we blew up the ones they were driving. Laminated glass doesn't fare so well against a GBU-12.
