>>9778774>suffocate Fun fact, during river crossing the T-72's engine took air through the crew compartment, so after waterproofing the tank they had to make sure to leave at least a hatch or the turret breech open to prevent suffocation.
This was no longer an option on the T-80 with its air-thirsty gas-turbine, so they just had a separate snorkel for the big-ass engine deck intakes.
