The ONLY thing I don't like from a game point of view is this means there aren't less powerful Imperial mooks (Army Troopers) to throw at players. But, I suppose I can make the security guards (previously naval troopers) more common and make them the mooks found guarding outposts, ships, space stations, etc.
Consider that the US Air Force has the world’s largest police force as security guards at all their air bases around the world, and if you considered them to be an "army", they would be the world’s third largest.
But those guys really are trained like police officers and not soldiers, although they did go through soldier-style basic training.
I imagine that the Navy mooks are much the same, just on a smaller scale.
