Directing fire.

Canadian Army Warrant Officer Robby Fraser, a platoon warrant officer with Princess Patricia's Canadian Light Infantry, directs machine gun fire at a support by fire position during a platoon-size live-fire assault, July 22, as part of Rim of the Pacific 2012. Approximately 2,200 personnel from nine nations comprise Special-Purpose Marine Air-Ground Task Force 3, Combined Force Land Component Command. The land component of RIMPAC is conducting amphibious and land-based operations in order to enhance multinational and joint interoperability.

Interesting.  A platoon warrant officer.  The Marine Corps could benefit from such a program.  It would allow experienced SNCO's to lead platoons.  It would never fly but it is a thought.
