It would seem the Russians are preparing to launch a "Take Over" Offensive Maneuver on Ukraine.

This winter Russian military has been showering Ukrainian territory with bombs and drones, relentlessly.

It would likely follow a wipe-up operation to secure occupation of the land.  But we know that the President of Ukraine and his men stand in the way.  Russian mercenary forces would lead the way in an effort to break through Ukrainian defensive lines, and assumedly, the "new" Russian recruits would secure captured land in a mop-up operation.

The missing piece in this scenario of a display of Russian aggression is a "welcoming contingency" of Russian sympathizers and sycophants within Ukraine that is awaiting the signal  to emerge from their cells and terrorize Ukrainian citizens loyal to the Ukrainian government.  It is well known that there are such individuals or groups in Ukraine willing to do Russian bidding.  (Or, they could be dropped in via plane in the dark of post midnight hours.)

In an effort to counter the possibility of this scenario ever happening, I would think the Ukrainian freedom fighters should rig the country roads from Russia with explosives and have shelters aplenty to protect the Ukrainians from personal assault and injury by the ample presence of the Ukrainian military.  The need for a well-trained Ukrainian military intelligence is obvious.

Tanks in possession of the Ukrainian soldiers would sure be helpful also to do battle with the onslaught of Russian ground-forces that is implied, if this eventuality were what Putin and his armed mercenary cohorts were emboldened--namely, a want on their part to take over the whole of Ukraine or a major portion thereof.
