Then it threw me for a double loop hehe. Typically I imagine SOG guys wearing ODs or tigerstripe, I'd completely forgotten that they got their hands on ERDLs. I guess what I thought was a Ka-Bar must be a pilot's survival knife.Picture is MAC-V SOG (Studies and Observation Group), which was comprised of special operations operatives which in the day (later 60s - mid 70s) were running top secret and covert operations in Cambodia and Laos. Members, including personnel from all services, were authorized to use any weapons and the weapons of choice included AK-47s and modified M79 grenade launchers. As shown in the picture the M79 stocks were chopped (Shockwave style) and the barrrel mounted sight removed. Information on this operation was closely guarded until the 1990s and the Pentagon Papers.
If any of you would like to read an overview of this unit take a look at this link.
John, sorry to hijack your thread!
While not mentioned on that site Operation Eldest Son is a favorite of mine. Really sneaky and still having repercussions today amongst terrorist organizations hehe
On that note the Shockwave really does seem like something they would have used back in the day.
