Good afternoon, I passed my test last week, and passed for both Warfare Specialist Sensors and Tactical. I have look at both of the job descriptions on the Royal navy website. I have my interview coming up in the following month, and need too choose one of them. I downloaded both PDF's, but it seems to state that TSM's also listen for possible threats. It says electronic listening equipment, Is it as advanced as Sonar? What i have also found are that SSM's are " trained to use highly-advanced active and passive sonar systems to detect other submarines and ships". And tactical will "use a range of advanced systems, including radar and electronic listening equipment, to identify and track potential threats and targets". What i am wanting to ask is, is Tactical a more rewarding and interesting career? As it seems that there is more use of different systems? But does that mean TSM's have sub branches within it? as it seems you get more experience with different systems? Thanks in advance. Razzy. P.s I have also used the search function, but couldn't find any threads on this, only people asking who else is joining the branch.
