Sorry Sketcha, friggin connectivity via satellite sucks! But it's back up!
Anyway... on to the question. I don't know. 🙂
I only know that my screen name is a Navy abbreviation for my rank, rating(job) and designator(air/surface/sub).
The MA = Master-at-Arms (this is what the Navy calls MP's)
The CS = chief, senior (this is my enlisted rank, E-8)
The (SW) = Surface Warfare qualified (which means I know a little bit about a lot of things)
