This commander was stationed at the Wakh Sind Barracks at the time Venom Snake arrived in Northern Kabul. He was identifiable for his red beret. He was later replaced by another commander.
Behind the scenes
The Wakh Sind commander is a fairly minor character in Mission 1: Phantom Limbs. Extracting him completes the related mission task though it is impossible on a first playthrough, since it requires the Fulton extraction device and/or calling for a chopper for direct extraction (both of which are unavailable until after Miller is rescued and the player completes the next mission).
If the player interrogates him, for unknown reasons, he will give the location of the commander as if he were a separate person.
