The city of Lodz was the immediate aim of the US 5th ID, they were driven back westwards to Kalisz by the sudden arrival of all those extra Soviet and Polish units. Most of the 5th never even saw Kalisz with the 256th Brigade being overrun before Divisional HQ reached the town.
Many encounters in T2K are not with armoured opponents. With a machinegun added to the loaders hatch, they can participate just as much in combat as the gunner (coaxial machinegun) and commander. The PC driver should be asked to make fairly regular driving rolls when in motion to reflect their ability to read the terrain, keep the vehicle in cover while also allowing the weapons guns to be brought to bear. Can be quite a stressful time for them if they get it wrong and everyone's yelling at them to a) get them out of the line of fire or b) get them into a position where they can shoot back!
Desert Storm is touched on in the 2.x timelines.
