I'm so glad this topic was broached. I'm surprised I hadn't thought of the potential difficulties. And love the stories. 🤣
I've been a motorcyclist for 25+ years, ride ATGATT year 'round, which can make potty breaks complicated. For long distance trips in my younger days, I used a Stadium Pal, but omitted the collection bag and ran a tube out my pant leg. Maybe that could be an option for some long duration troops? But also, warm bag of pee strapped to your leg... Not sure if that's covered in the CRL.
