They'll try to blame it on somebody.
its literally in the article what happened though
if a massive recovery vehicle like that goes under and rolls,
you're going to die. especially if you're wearing any amount of gear. also i kinda doubt the vehicle would just lose signal and power completely if submerged too. for a large exercise, as long as its still pinging something then its possible others wouldn't have even realized the danger or that the team was missing.
also the ukr war has taught everyone in the region the value of recovering armor/tanks whenever possible hence the polish/lithuanian/estonian counterparts being tagged as well.
