Exchange.

This is coolbert:

"'Most of the released Ukrainians have serious injuries,' . . . 'gunshot and shrapnel wounds, explosive injuries, burns, fractures, amputations of limbs.' . . . 'all of them [did?] receive proper medical and psychological assistance.'"

"Ukraine, Russia Each Swap 144 Soldiers: Largest Prisoner Exchange in the War"

"Ukraine and Russia announced Wednesday they would exchange 144 soldiers each, making this the largest prisoner swap since the war began in February."

[....]

"According to Axios, of the 144 soldiers returning to Ukraine, 95 of them fought in a months-long battle to defend the Azovstal steel factory in Mariupol, which, according to sources, was the last foothold of Ukrainian resistance in the city."

The surrender of Ukrainian troops Mariupol was several thousands total. Including those taken prisoner in the aftermath of the Azovstal steelyard siege.

To what extent exchanged prisoners are subject to parole as that word understood in the military context not clear. If indeed even a factor.

"Parole is 'the agreement of persons who have been taken prisoner by an enemy that they will not again take up arms against those who captured them, either for a limited time or during the continuance of the war.' The US Department of Defense [DoD] defines parole more broadly: 'Parole agreements are promises given the captor by a POW to fulfill stated conditions, such as not to bear arms or not to escape, in consideration of special privileges, such as release from captivity or lessened restraint.'"

Parole a quite common procedure during the American Civil War. Has been used quite sparingly since then. American DOD definition of parole in response to the behavior of American soldiers being held captive during the Korean War. Certain American POW Korea their conduct less than desirable.
