Understanding the Military "M" designations
Does anyone produce a chart that lists in order the description of "M-1" though "M-203 Grenade Launcher" equipment designations? M-1, M-14, M-16, etc., are so common. Is it possible to find a source so I can become familiar with the many others? I picked M-203 as the upper limit only because that is the highest one I know. I am sure there are a lot of obsolete/dead projects that must have "M" designations. I would be fun to learn what they are.
Anyone find a source for a chart?
