It has been mentioned a couple of times that users may not just fly an airplane, but also control other objects. See one of Oleg's latest replies:

Question:
Secondly, will Storm of War allow moving objects (tanks and ships) during online play? This cannot be done in online play with Il2.

Oleg:
It is done in Il-2 in all online modes except Doghfight mode. In BoB will be special Doghfight mode (one of dogfight modes), when some of objects also will be moveable and even controllable by user.

------------------------

This doesn't mean SOW BoB will include a FPS, but at least the game engine will be open for this sort of thing... Let's speculate what "objects" besides aircraft we get to control:
Flak guns? Tanks?
