The sniper lit the cigarette for a few reasons.
- To calm his nerves: The act of smoking can provide a sense of comfort and relaxation, especially in high-stress situations like combat.
- To break the monotony: The sniper's job often involves long periods of waiting and observation. Lighting a cigarette can be a way to pass the time and break the routine.
- To obscure his location: The smoke from the cigarette can act as a visual distraction, making it harder for the enemy to pinpoint his exact position.
It's important to note that the specific reason for the sniper's actions will depend on the context of the situation.
