I've always wanted a BTR-80, but it is difficult to get one in my country. I didn't know that that there are a BTR-90 until a couple of days ago. I've searched for pics in the net and have found a good bunch of them, I've even found a paper model that can be used as a basis for scratchbuild. The point is, I've found several pics of BTR-90, but I've identified at least three different types of them, with some differences between them. Here they are:
Type one:


Type 2:



The vehicle in the two first pics seems to be up-armored in the turret ring zone. The papermodel is mostly like this Type 2.
Type 3... Not exactly an actual vehicle, but the blueprints:

*EDIT* A pic of type 3:

As you can see, all different between them, the question is: Which one is actually in service? Maybe one of them is a prototype or pre-production vehicle, I want to know it as well. Best regards.
