What happened to the 155 and 8 inch of Vietnam era?
Well, we still have 155. But I think all the 8 inch is gone. At least those 8 inch long barrels are long gone. I don’t know if they kept any howitzers. Maybe they are rattling around the arsenals of allies we gave them to?
Well, I know 12th Marines decommissioned their last 8" battery in 1985 because my battery shared their building. At that time, we were using Vietnam-era M114 pigs, 155mm, but were in the process of replacing them with M198 155's around that same time. Now, the M198's have been replaced by the M777, also a 155mm.
