Morphology

communication + trench

The meaning is directly derivable from combining 'communication' (a channel or passage) with 'trench' (a long, narrow defensive ditch): a trench used as a protected passage. Although a technical military term, the noun+noun composition follows normal semantic composition and would be understandable to a B1 learner who knows both constituents.

Etymology

Communication trench comes from soldiers digging a trench for communication, a protected path to send messages and move safely between the back and front lines. That's why it means 'a protected passage between the rear and front lines'.
