I liken being tattooed by someone without tattoos to being led into combat by an untrained civilian. First off, when you are a soldier, and I was one for 6 years, you want your leaders and battle buddies to have the most training possible. An artist with little or no tattoos has little or no "training" IMO. Secondly, there is an unspoken bond that soldiers have through their shared experiences that civilians can't understand. It's the same when an artist is tattooed, the tattooed artist knows what you're about to endure, you share that bond with him/her.
