Re: The M-9 Bayonet .
The M-9 is a marvel of modern military thinking.
Both the U.S. military and the Russians found the same solution for the same problem with this style of Bayonet.
In the early 80's we thought the next major war was going to be in the European theatre against the Russians. Our leaders knew two things... on a long campaign soldiers throw away everything they think is useless, and at the end of an assault there was going to be fixed obstacles in the way, dragons teeth and concertina wire.
Their worry was that at the end of assaults when we got to the wire, most soldiers would have pitched their wire cutters long before.
How do you make a soldier lug around a pair of wire cutters for weeks or months? The answer: disguise them as a knife!
Most people in the field will throw away everything they have before pitching their knife. It is primal and bred in us.
So we got our M-9, and the Russians got theirs. They are both horrible knives, both as a utility knife and as a fighting knife. As a bayonet it is almost useless. But the military leadership doesn't believe we will ever be in close combat in modern warfare. Not knife close or bayonet close anyway.
The M-9. A useless knife and terrible bayonet
But a fantastic wire cutter.
