Back in the 90s they hired a female Marine--
The install was a hard one, and many had failed at it. I warned her that she WOULD have to call me, and then even I would probably have to help her futz with it for a while. Just a lot of options- and experience was required. But you don't get it without trying, so I had her try
She called. She was crying. Real sobs.
Yes, I am sure it was frustrating and infuriating, because this product just was. I told her it would be.
But if a difficult config/install had her in tears, where the only pressure she was under was time ( she had 3 days for the install) and her own will to succeed ( she called on day two) - how could she possibly have be calm and helpful on a battlefield?
Not being able to do pullups is the least of our problems with the female marine corp.
