We have women in all trades here in Canada. So, some observations;
Personnality type A. A fine tanker, can swing a sledge better then most guys, but in the end got frustrated because the guys still wouldn't let her do her job and got out. Type A is VERY RARE.
Type B. A fine tanker, could pump the rounds into the gun faster then the gunner could fire them. Did her 3 years, proved that she could do it and got out. About 40% of the women that get in seem to do it just to prove that they can. Very poor return on investment from the Army's perspective.
Type C. Dedicated, kept plugging away, made Sgt in 15 years, (took me 17) and knows her shit. And the Regiment sent her to teach, while her husband has done 5 tours now. I'd be ballistic if I were her right now, but it's hard to get past the "protect mom DNA strain."
Type D. Got in to prove they could, couldn't so the guys pick up the slack. About 40% of the girls fall in this category. BUT, about 30% of the guys do too. So be fair, not everyone can do everything. Sprocket bolts take 100ftpds of tourque. I wieghed 220 pds. Just the thought of getting that tourque wrench out was enough to make my back hurt.
So, can women be tankers? Yes, if the guys would let them. But in the end, I think evolution hasn't caught up with our Politically Correct Idealism. GUYS still need to evolve abit.
