At 0:22, that's a very small bomb
It was just a show pyrotechnic... it is still a fairly new toy so I doubt they would want to scratch it... yet.
Why not have both anti-radiation liner and kevlar anti spall liner ? One
never know when they would encounter operating against a nuclear
backdrop or going into places that have been nuked few hours back.
For all we know they might have left the anti radiation liner in place and put the anti spall liner over top. Most exported vehicles didn't have anti radiation liners anyway.
As long as they are keeping their tactical nukes I guess it makes sense to keep preparing for such things.
After all in Desert Storm the threat of bio and chem warfare was very real.
I'm guessing it's more likely to encounter fragmentation than it is to encounter NBC environments.
Yeah... looking purely mathematically at it I would say odds are any real use of the vehicles will likely involved the real threat of fragmentation and penetration, while any NBC environments might be faced once if ever.
The spall lining is useful against HESH warheads because the kevlar captures any of the armour that peels off and would normally do internal damage. It is also useful against 90% penetrations where the incoming round almost but doesn't quite penetrate as that can lead to parts of the armour on the surface where the penetration would have occurred from spalling. And of course with an actual penetration the kevlar can sometimes stop the projectile but more often will at least stop the particles of armour coming into the vehicle with the penetrator so internal damage is reduced.
Does BTR-82 have better mine resistance comparing to older BTRs? For
sure kevlar liner will improve armor capabilities, how much, depend on
the ticknes of kevlar liner.
It all depends on the type of mine. The average anti tank mine or anti personel mine with most of the BTR series just resulted in a wheel being blown off. The vehicle could usually drive away... because the tire took most of the force and damage. For a mine that might explode under the belly... either a magnetic mine or remote controlled mine the vehicle is not so well protected. Fitting the seats to the walls or ceilings of the vehicles improve the chance of survival for the crew and troops because a seat directly fixed to the floor will channel the energy of the explosive right up through anybody sitting on those seats and most likely crush their spines and kill them. A seat fixed to the wall or ceiling will break and the distance between the seat and the floor will absorb a lot of the energy of the explosion... so the person sitting in that seat will be able to survive more powerful explosions. Obviously if the bomb is a 500kg aerial bomb with a remote fuse then nothing will walk away. Kevlar liners will reduce spall and any fragmentation from entering the troop compartment and might also slightly soften the impact as the seat hits the kevlar. For its weight and cost kevlar lining is very much well worth it.
