Tank Crew Losses

The table is a bit weird, since tank commanders are all lumped into one category, regardless of tank, and IS-2 radio "masters" are included (presumably off-tank repairmen, as the IS-2 had no dedicated radio operator). Anyway, it lets us make some conclusions regarding the safety of each crew member. The radio operator's job on the T-34 and T-34-85 was three times safer than the driver's, despite a lack of personal escape hatch. You'd think that both the driver and the radio operator are safer than the turret crewmen, judging by 46 dead loaders on T-34 variants compared to 11 radio operators or 33 drivers, but the loaders died more than gunners did (looking at the T-34-85 alone). The T-34 gunner/commander is lumped in with the other commanders, so it's hard to judge how safe his position was.

However, percentage wise, the numbers aren't so bad. Over 117 lost T-34 variants, the radio operator has a 10% chance of dying, the driver 28%, the loader 39%. T-34-85 gunners have a 27% chance.

By comparison, the IS-2's driver has an 18% chance of dying, no loaders died at all, and the gunner also has an 18% chance of dying if his tank is destroyed. 11 tanks isn't a very large sample, however, so it's hard to make judgements.

With a similarly low sample size, the M3 Lee's radio operator has a 23% chance of dying, the driver has a 15% chance, and the gunners and loaders are in poor shape: 77% and 85%, respectively. 

Let's compare this to figures from report ORO-T-117 "Survey of Allied Tank Casualties in World War II", gathered by the American First Army in Europe.
