ZSh-3B - combat version of the ZSh-3 helmet used by helicopter and ground attack pilots. It's made out of ballistic titanium and while cannot stop a direct bullet hit, it provides excellent protection against shrapnel. Another difference between the ZSh-3B and the original helmet was the introduction of dual visor system. The main visor is just like the one on the original helmet, but is made out of clear plastic. Again, just like the original, this visor is operated via a three-position flip, but would usually be kept in the "down" position during the whole flight. Second, smaller visor installs over the main one and is made out of charcoal colored plastic. This visor does not have a position flip and can be lowered in any desired position by simply pulling it up or down.

ZSh-3B comes only in sizes 1 and 2.

 

ZSh-3B set. This one is made to represent the outfit of Soviet helicopter pilots during Soviet involvement in Afghanistan from 1978 to 1989 - it includes the ShLO-82 leather helmet, green body KM-32 mask and La-5 throat microphone.
Same helmet; small visor is in up position.
Helicopter pilots did not use occipital bladders, so it's not installed in this setup. Also note the three-position flip for the main visor - it's just like those found on regular ZSh-3 helmets.
Small visor is completely down.
