MIL-DTL-46177 is an older, now-replaced standard for a high hardness steel RHA. [4] It specifies a harder steel that is nearly identical to AR500 in terms of tensile and yield strength. [5] The Brinell hardness of AR500 is in the 477-534 range. MIL-DTL-46100E specifies a steel of identical hardness. [3] MIL-DTL-32332 specifies ultra-hard steel ...
This type of bullet-resistant glass has been in regular use on combat vehicles since World War II; it is typically about 100–120 mm (3.9–4.7 in) thick and is usually extremely heavy. Newer materials are being developed. One such, aluminium oxynitride, is much lighter but at US$10–15 per square inch is much more costly.
Dominator 1 was modified from a 2007 Chevrolet Tahoe that was used during the 2008 storm chasing season and debuted in the 2009 chase season. The modifications included adding bulletproof sheet metal and transparent Lexan armor to protect against flying debris near tornadoes, and an external roll cage and racing-style safety harnesses in case of a vehicle roll.

TIV's armored shell consists of 1/8–1/4 inch steel plate welded to a two-inch square steel tubing frame. The windows are bullet resistant polycarbonate, measuring 1.5 in (38 mm) thick on the windshield and 0.5 in (13 mm) thick on the sides. [2]
Side SAPI (SSAPI, S-SAPI) torso side plates are only in 6 in × 8 in (150 mm × 200 mm) size, and weigh around 1 kg (2.2 lb). [13] The replacement for the S-SAPI in U.S. Army, the Enhanced Side Ballistic Inserts (ESBI, E-SBI), originally had only the 7 in × 8 in (180 mm × 200 mm) size, Small and medium were added later on.

Bulletproof glass of a jeweler's window after a burglary attempt. The Mona Lisa behind bulletproof glass at the Louvre Museum. Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles, although, like any other material, it is not completely impenetrable.
The plates were 2 mm thick and weighed 3.5 kg (7.7 lb). This armour was generally supplied to assault engineers (SHISBr) and tank desantniki . The SN armour protected wearers from 9×19mm bullets fired by an MP 40 submachine gun at around 100 m (110 yd), and sometimes it was able to deflect 7.92 Mauser rifle bullets (and bayonet blades), but ...
Most overt armour plates usually are sized to 250 mm × 300 mm (10 in × 12 in), 280 mm × 360 mm (11 in × 14 in), and other such dimensions, however SAPI plates are slightly different. [4] In addition, armour plates may be curved to assist in the user's comfort and ergonomics.
