I am working on a fiction novel that takes place in Afghanistan. There is one scene where a sniper is providing overwatch for a fire team about to make entry into a building. I am looking for accurate information on how the MUNS operates going from viewing the exterior of a building at night to looking into windows where the interior rooms are light up.

A plus would be to discuss with someone who knows actual Marine Corps sniper training training and weapons. I was in the Marine Corps, deployed to Iraq in 04 as an 0331 machine gunner. I don't want to write an inaccurate scene because I am not familiar with specific gear.
