"Private, I don't give a f*ck if your feet are bleeding ranger up and finish this ruck march."
"Bro, this chick is super hot but shes got a fat friend who needs a companion, ranger up and be a wingman"
"Half of my equipment is broken, people are shooting at me, but I still ranger up and keep humping along"

Someone who shops curbsides, trash bins and dumpsters for useful or valuable items, often items that just need to be cleaned slightly to appear new again. A treasure ranger is always on the look out for free stuff during their daily lives and does not like the terms "dumpster diving" or "trash picking" because they don't go to places just to search through the trash, but instead have eagle eyes and will divert course to save a cool thing from it's landfill fate.
