...I imagined "involuntarily parked", with no handy supporting vehicles or (perhaps) the respite to use them.
And the rookie error of not examining/preparing the ground upon which to rest up/operate in-situ is probably something well trained out of the current forces. (The danger may now become one of apparently frozen but imminently thawing ground, but the morning Sun isn't likely to penetrate so deeply into semipermafrost.)
Possibly, more likely, is setting up in a dip/ditch in the ground which the immediate slight thawing of the area causes to reveive disproportionately more runoff than expected. Having myself set up a tent half way up a mountain in a hollow (with the
latest in a series of a scenic views of another mountain) and then by morning discovered that a significant trickle rain/meltwater tended to flow through the very spot I was pitched... Didn't make that mistake twice, albeit that I'd doubt this experience alone would make me any better at successfully laying up an AFV in good order in a (near-)combat situation.
Also, I meant to add (and the real intent of this new post) that tracked vehicles actually stuck in mud might yet dig
themselves out once the mud is frozen. So long as the drivechain and tracks themselves aren't gripped too hard in the ice itself. It's when
wheels (and typical chassis protusions) of a vehicle are axle-deep in now-frozen depressions that you might need more than enginepower, and perhaps some handy bundles of vegetation, to (eventually) extract yourself. But this is going to be something that experienced commanderss/drivers will know much more about and pass the subtleties on to their more green compatriots.
(Not sure what the mix is between 'veterans' (of at least a year) and greenhorns, in the respective armies. I get the impression that Russia is more likely to build up units with a greater concentration of the latter, as time goes on, while Ukraine is heading in the opposite direction.)
