Morphology

line + officer

The meaning 'a commissioned officer in a combat unit' is directly derivable from combining 'line' (a forward/front troop position) with 'officer' (a military rank), yielding an officer assigned to the line. Although it is somewhat specialized military vocabulary, the noun+noun composition is straightforward and cross-linguistically common, so a B1 learner who knows both constituents would likely infer the intended sense.

Etymology

Line officer comes from the idea of the line of soldiers at the front of a battle. A line officer was an officer who stood in that front line and gave direct orders, so today it means an officer in a 'combat' unit rather than a 'staff' or 'supply' officer.
