Lask it is
Chaps, I see the young lady has a point. We've got to have some fuel for the UAZ or some horses to replace it. Some pack horses mightn't be a bad idea. I'm not so worried about disrupting the unit, despite that being in our original orders, because they're probably already fairly disorganized as a consequence of the fighting.
Nonetheless, they are still a force to be reckoned with. If we have enough Pact Uniforms, it would be ideal to have the entire team dressed thus. Standard British DPM or Yank Woodland Pattern will tend to attract the eye.
Perhaps we might (with the right weaponry) masquerade as a Spetznaz unit who have been operating to disrupt the NATO forces, as these are often attached at the Brigade, Division or even Army level. Of course, if we all speak Russian or Polish, this would explain our mixed equipment.
I think anyone who cannot speak neither Polish nor Russian ought to be assigned to continue gaurding the gear and the civilians, perhaps even starting a movement westward. We may have to abandon the UAZ - we'll be out of food shortly so that is more important than the vehicle. The wounded can be carried on litters.
So, let us assemble a small group of Russian or Polish speakers, see to it we are primarily outfitted with Russian or Polish equipment, discard most of our NATO-esque details like dog-tags, letters home, etc. Anything that would identify you definitively as an Allied soldier.
Then, under the cover of darkness, we infiltrate Lask, attempt to covertly acquire supply and perhaps further transport.
And try hard not to let the blighters kill us all....
