UH-1C Huey "Frog" Ace of Spades, Sharks Gun Platoon, 174th AHC, Vietnam (1:72)

There were 766 Bell UH-1C helicopters built in several equipment modified variants. One was the '_Frog'_ equipped with side-mounted XM-158 twin rocket pods each holding seven 2.75 inch rockets. The "M-5" fitted the gunship with a nose turret mounting an M-75 40 mm automatic anti-personnel grenade launcher that held 300 anti-personnel grenades. The crews referred to these as '_Chunkers'_ because of the sound when the grenades were fired. The infamous '_Shark'_ gunships were created in 1966 when permission was granted to use the fearsome looking '_Tiger Mouth'_ on the front of the Hueys.

In 1971 the 174th AHC was part of the disastrous Operation Lam Son 719 in Laos. On Wednesday March 3, 1971 UH-1C #64-14170 '_Ace Of Spades'_ was crewed by pilot Gary Harter, co-pilot Morgan Mills, door gunner Pat Wade and crew-chief Bob Jansen. UH-1C #170 and another UH-1C were flying escort for some news people as well as supporting an assault on LZ Lolo. During the action both '_Frogs'_ were brought down by fire from multiple guns in the area. #170 landed beside QL9 (Highway 9 '_ a dirt road) and the crew were safely picked up.
