The United States Marine Corps's division reconnaissance battalions, or commonly called Marine Division Recon, are the reconnaissance assets of Marine Air-Ground Task Force that provide division-level ground and amphibious reconnaissance to the Ground Combat Element. Division reconnaissance teams are employed to observe and report on enemy activity and other information of military significance in close operations. Their capabilities are similar to those of Force Recon, but do not normally insert by parachute.
The division also has other substantial organic reconnaissance assets. The Scout/Sniper platoons may be attached to regimental reconnaissance battalions to provide long-range precision fire superiority. These sniper Marines function as recon assets as well to provide surveillance and target acquisition to the Marine Expeditionary Force (MEF), known as STA snipers. [Wikipedia]
