Playing this again because of course I am. Just dispatched these two cretins and found myself wondering... how the hell did they get there??

We happen upon them whilst exploring the ship here...


However, when we arrived at the Gelnika, there was no other submarine or vehicle in sight?


They were not wearing any kind of scuba gear. They were just in usual black-suited Turk garb.

Please can someone who is knowledgeable in the extended universe answer me this?
