I was a Tank Commander and this is a 4 man tight knit crew, Tank Commander, Gunner, Loader and Driver. You are out in the field for months, you live on the tank. Maintenance on a tank involves heavy tools, and track segments are very heavy. A 100 lb lady is not physically able to assist the crew and it means the male crew members have to work harder to take up the slack. Women will break up the cohesion of the crew with jealousy and sexual desires. Tank crews work together and train together and all have to pull their weight. Pregnancy breaks up and weakens the crew. You depend on each other in combat. There is no time to stop for personal hygiene. Women on tanks will not work!
