Should VRISS/Arena be restored ?

...Has anyone anything about that?

Its not bright yellow paint that is spewed out in the picture above. But it may just be that its only Sweden that uses WP in the close protection of its armour.

Better picture


Then we have the artillery and their gigantic smoke rounds, that would indeed hurt...

Hi; I am an ex-zipper head (tanker).

The smoke grenades land about 20 meters in front of the vehicle. There is no shrapnel effect from the discharging smoke canisters, and even if you were hit by a canister it would only leave a good lump and bruise at the most.

I am not sure about the VIRSS shot though, we didn't have those on the Leos when I drove.

I think its standard today. Today most smoke dischargers are armed with VIRSS (Visual and InfraRed Smoke Screening System). It offers a 1-2 minute smoke screen 20-50m in front of the vehicle. The smoke itself is thick hot smoke that contains small metal fragments to disrupt even active sensors.

Shouldn't some of the U.S. vehicles have VIRSS in the oobs, or do we not use it at all?

Most modern AFVs have IR-screening smoke pots, but the principle of the VIRSS system in the game is more sophisticated than that.

It is meant to be linked to various sensors (laser warning recievers, flash detectors, milliwave radars...), which automatically detect incoming missiles and spread the smoke layers, plus in some cases high energy flashes or laser jamming.

So it doesn't boil down to advanced smoke pots, but it also needs the whole electronic suit, which many countries haven't fielded yet.

Some russian systems not just fooling but actually destroying missile. "Shtora" is a pure VRISS. Drozd/Drozd-2 (also reperesented as VRISS in the game ?) is a turret mounted 180 degree system of mortars. Arena is a more interesting device. Mounted on top of the turret it is a ring of vertically launched rockets. Each rocket covereing a part of 360 degree sector. Then incoming missile in the range rocket launched up and warhead shooting projectiles down at the missile. Both Drozd and Arena guided by milliwave radar.

Noppe, you are confusing two things: VIRSS is active non-destructive jamming of incoming missiles and firer's sensors.

Drozd and Arena, and any other projectile-destructive device are represented the same way in the game: it is all termed ARENA. Presumably since pivoting the vehicle is not counted as move (don't even ask for it, the code won't be changed on this), the system covering !(= or �&=� makes no difference since the vehicle can point to the new direction immediately.

Anyway I guess you can model this angle difference by assuming the "ARENA 1 shot" is a Drozd-like system, as opposed to the all-around Arena.

US AFV's use 66m smoke grenade dischargers which have to be manually fired. They launch the 66mm L8A1 Red Phosporus grenade, which is a thermal smoke grenade, designed to defeat or at least degrade thermal imaging. The M1 series tank uses two 6 tube M250 launchers - one on either side of the turret. The M2/M3 Bradley IFV, USMC LAV-25, the Stryker family of vehicles, M113A3 all use the 4 barrel M257 launcher. I'm not sure of the incindiary effect of the L8A1's vs. troops, but I've been told they can start fires.
