Yeah, get rid of the LDOs! Marc is one in a long line of top-notch LDOs that for many years formed the technical core of the Navy/Marine Corp cryptologic community — notables include Clyde Lopez, Kevin Hooley, Tom Botulinski, Jim Newman, Al Ross and a host of others. There are other routes to a commission from the senior enlisted ranks, but our LDOs are/were a vital part of our officer corps. Eliminating the LDO route for cryptologists was not our best move.
Congrats to CAPT Ratkus on his retirement.
