From multiple journeys with a large team on a V3S, we lost more men on hypothermia issue than to enemy gunfire. Heaters are there on the model. Do try to incorporate a function to turn on the heating to at least maintain the homeostasis of the players at a neutral level.

Otherwise, on a rainy day, a journey from Severograd to Berezino will drop all passengers into a irreversible level of hypothermia, regardless of their clothing (for the record, we had military grade jackets, even raincoats - nothing helped).

Hopefully, you will implement the heating function on all the upcoming vehicles that will support it.
