IM:UC BMD-1 and BRDM-2 Screenshots and a question

Hottentotten Mike from the IM:UC Mod has informed us that they posted four new interior screenshots of their BMD-1 and BRDM-2 in the BI Forums.

However, they could need some help concerning the position of the BMD-1 cargo seats, if you know this kind of vehicle or have interiors shots contact them in the BI Forums.

Quoting fas.org:
An internal NBC filtration system provides protection for the three-man crew and four combat troops. Two squad members, including the squad leader [= commander of the bmd], ride in the two hatch positions on each side of the driver, while the remaining three occupy the compartment between the turret and engine.
where are the other three (four?) cargo seats exactly? as you see on the pic i only found sufficent space for two seats (look pic below).
