I don't understand why you are suprised.
It should be no news to you guys that i am totally insane when it comes to helicopters and especially Attack helicopters.
I researched quite a few things about attack helicopters and for example the AH-64,AH-1, CSH-2 Rooivalk and Tiger EC665 all use the same cockpit glass made by the company "PPG Aerospace
This file shows what kind of "bulletproof"
glass the Apache exactly uses.
It says, it uses mainly acrylic
"plastic" sheets and "polycarbonate
" which is nothing else but a reinforced plastic
The company PPG Aerospace
itself differ their products in "Transparency Armor"
which only sell bullet proof glass for ground vehicles such as Hummvees.
Go on www.ppg.com and "Transparencies
" and than go on "Military Aviation
" and "Military Aviation Programm
" all aircrafts are listed use only Non bullet proof glasses.
It is a ballistic shield to improve performance and safety for pilots explecit against shockwaves from MANPADS
and low protection against impacts of flying around parts, but not direct impact from a projectile nor fragmentations of any kind of Warheads.Also the current bulletproof glasses in military regardless of what kind of vehicle are all made of sheets of real glass and plastic foils/sheets and weight alot, for those of you who don't know, glass that isn't flat can't be bulletproof like side windows on Mi-24 which are just reinforced acryl glass same as AH-1 and AH-64 side and top windshields
, the Apaches Flat windshields infront of each Pilot have a few more sheets thinner and are flat to improve the transparency and visibility for the pilots, they also have higher crashworthiness and more resistant to scratches to endure a high optical quality.
The only thing on the Apache (or better to say inside of it) that is bulletproof is the single bulletproof sheet that is located exactly behind the WSO's head that seperates both cockpits, it is believed to withstand 12.7mm ammunition, but from the look of it from various videos and pictures it should only sustain fire of 7.62mm. I can be wrong about this but what i could see it looks like about 1.5cm thick, while 12.7mm bulletproof glass of Mi-28 is about 45mm thick
1st Lt. King survived the single AK-47 round that hit his left side cockpit glass and hit his throat.
And the video you have posted was translated by me.
PS: What i almost forgot to add.
Western countries have a very odd design of ballistic protection for their Pilots.
For example everyone knows how russians do it, they entirely bulletproof the cockpit from almost all angles, while western designes such as Apache or even worse the Tiger use only seperated ballistic protective armor sheets inside the hull centering around the pilot itself, instead of making the entire fuselage around the cockpit section bullet proof like russians do.
If you don't know what i mean look on this side picture from this side about AH-64 Apaches.
Of course the Aviation bay beneath the crew is protected by itself, but for example exact beneath the pilot is unprotected the Ammunition storage of the M230 cannon or the "robby tank" the 3rd fuel tank that can be installed to improve endurance but cuts of the ammunition from 1200 to 300 rounds of 30x113mm B.
The Tiger is one of the worst with even more laughable protection design. For instance, the german EC665 Tiger PAH-2 was reported (without proof) that the Bundeswehr (Bundesamt für Wehrtechnik und Beschaffung) which means "Federal Office of Defence Technology and Procurement" had purchased Tigers without the standardized armor but ordered a "lite" version. First this report sounded totally stupid but their was afterwards signs that it maybe true. Since they purchased ASGARD-F upgrade package which implemented armored steel sheets which were mounted to the pilots site of the fuselage.
And now comes the weirdest point of the ballistical protection of western helicopters, since the armor is scathered around the helicopter the crashworthy seats of the pilots are armored from sides to compansate the rather thin armor. It maybe not a big issue for Apache sins it has a 2 layered cockpit with a titanium alloy cockpit capsule or also called "bathtub" and than the outer skin that also gives the bird its more aerodynamic shape made of alluminium alloy same as Mi-28/24/Ka50/52, but the rest of western helicopters have a rather thin ballistical protection.
Just watch for example the A-129 which is so thin but were also advertised to be capable to withstand 23mm rounds, which i personally would not be so sure.
