The first is a custom version of the Star Trek XI ranks. There is a uniform difference ladies and gentlemen between non-commissioned and commissioned officers. This also makes the Ensign uniform distinctive =p. Check it out HERE
The second set is the awesome 2400 Series (Now with Alpha Channels)!!! This set has been in the works for a little while now and is finally complete.
