i wouldn't of minded seeing the structure after the defensive blast to see just how effective it was. Seems like a key bit to leave out of the clip. Seems quite effective, but its kinda hard to gauge by the glimpse of scorching you can see.
Still tho, I'm sure its better than a full on impact despite any residual concussion blast, scorching, or shrapnel.

#1 Consider for a moment how anti vehicle weapons, and armour works.

Armour is a sheet of thick metal that tries to protect the inside of the vehicle. Regular projectiles don't penetrate and explosions stay on the outside. So armour piercing projects exists. They try to puncture through as much of the armour as they can and explode inside the armour or in the vehicle if they make it through. Even the RPG generates a super heated jet ahead of it to cut through armour before exploding.

Current generation of tank armour is called Reactive armour. Basically explosive packs strapped to the outside of the armour. So when a projectile hits the explosive pack, it explodes on the outside of the armour, rather borrowing its way into it. While this scorches and dents the outside, it is enough to protect the vehicle.

Now this system moves that explosion a couple meters away from the armour, lessening the impact further still. While you might need a new coat of paint, the armour on the vehicle should be undamaged from the heat and shrapnell.

I remember seeing a similar system on Future Weapons, on an APC in the middle east. They were able to use a thinner and lighter armor thanks to the point defence system. In turn a lighter faster vehicle with excellent protection from tank shells and RPG's.

cant wait to see the weapon they invent to counter this kinda shield

#4 The system is based on doppler radar, so a radar jammer will render this ineffective. Also targeting the same side with several projectiles will deplete the point defence system of ammunition.

So...basically its a flying Claymore mine?

I know of an even better active protection. It's called "peace". Also known as "Let's stop acting like immature idiots get along and be nice"

#7 I agree with you, but we cant even all get along on snort here.

#4 one electric-railgun match faster bullets, render flying-claymore old.

in all fairness Sizzlik, perhaps #3 knows more than one language as well, just not the one in this video. o.O

And yea #2, I'm aware of all that, but it still doesn't change the fact that I would have liked to see some after effect footage as well to go with that sweet explosion.

#2 Just a quick correction. The jet of molten copper is the destructive force behind armor piercing missiles and RPGs. There is no secondary explosion occurring inside, the molten copper burns quite joyfully everything inside fast enough to be considered as an explosive force. Oh, there's explosives stored inside the tank too, you don't need to bring more explosive material in it.

This method basically explodes the shell before it can use it's shaped charge and inverted cone. Without that geometrical shape, it just explodes 360 degrees in all directions.

Hey number #3, why not better yourself and learn a little Russian

Works well until you are escorting people on foot.

It might be the Russian's "latest" armor tech, but it is still over twenty years old.

#4 It is called an Abrams M1A2 main battle tank.
