I work with a K9 search and rescue team now and then. The team is very good at going deep into the woods looking for missing and/or dead people on scent trails that are sometimes over 24h old.
One of the ladies used a black tactical rig full of pouches. But instead of gun stuff it held gps devices, radios, dog treats, toys, water, collapsible bowls and a dozen other things for her and her dog.
So we geeked out for like five minutes over how useful it was. It's a Condor Ronin Rig if anyone is curious
