The Cryptologic Technician Technical (CTT) rating:

Although U.S. military involvement in Vietnam had ended with the withdrawal of the last ground combat forces in 1973, the U.S. maintained close ties with the Republic of Vietnam government and continued logistical support of their Armed Forces. Missions flown by VQ-1 had also come to a close with the final withdrawal of U.S. military forces.

ENS Brian Madariaga is the last enlisted cryptologic technician (CT) to be commissioned as a Cryptologic Warfare Limited Duty Officer (LDO).  Congratulations on your commission and welcome to the Cryptologic Warfare Officer wardroom shipmate!  Below is ENS Brian Madariaga’s biography. 

The recent release of NAVOP 128/22 announced the suspension of the cryptologic LDO program, bringing to an end a path to a commission that produced some of the community’s finest technical managers and leaders.  Selection for a commission under this highly competitive program was based on proven cryptologic expertise and leadership, important in a career field where no corresponding college program existed.
