Marine Corps Force Recon teams are special forces assigned to carry out missions that Marine Intelligence deems most sensitive. The identities of individual Force Recon marines and other such information, such as the exact number of Recon marines in action at a given time, is limited to those officers with level 10 security clearance or higher. Recon marines were typically tasked with ground-based actions, while Starfleet SEALs typically handled ship- or station-board actions. (Star Trek: Remington)
