Does anyone think the Air Force will follow the Army's decision in now allowing full sleeve tattoos?

Not anytime soon. We seem to be going the route of making standards more strict.

I think ALL branches will follow suit. Tats are becoming more accepted in normal society and the military is slowly starting to "catch up."

I think the reason the Army cut sling in 1948, was so the Army Air Corps could do whatever they wanted in these types of matters...since they became the Air Forces has continued to whatever they wanted.
