Sea duty for the CTI is defined as the performance of their job on any subsurface vessel, aircraft of submarine.
The data they glean is of utmost importance and interest at the command and decision-making level.
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).
