The Singapore Armed Forces Commando Formation (CDO FN, ) is a commando formation of the Singapore Armed Forces (SAF). It is made up of only one battalion, the 1st Commando Battalion (1 CDO). A specialised offensive unit, it specializes in preemptive operations involving small groups of specially-trained soldiers in enemy territory.
