On the social news website Reddit, a newly-enlisted CTI inquired in the subreddit, r/newtothenavy as to what life as a CTI is like.

A 10-year CTI veteran answered him:

“I’ve been a CTI for about ten years now. I’ve deployed on subs which absolutely did mean spending 12 hours in a dark room either translating or listening to white noise. That’s also the job that got me to see Japan, Singapore, Philippines, etc.”

“I’ve also spent years as essentially a CTR composing reports, living a life barely different than a civilian. I’ve had a couple other jobs where language was useful but my primary duty was to be a subject matter expert on my region.”

“CTIs on the watch floor do spend a ton of time just translating, but there’s room to move up to more supervisory roles for those that want to.”

“I’ve also seen some go straight into being pseudo-CTNs, usually if they have a lot of network and coding experience.”

CTIs are required to prove their language proficiency yearly by taking the Defense Language Proficiency Test (DLPT).
