Yikes

They don't throw grenades or do land nav anymore?

Even my tanker ass threw two live grenades in the grenade course.

It's an interesting read and I've long held that spending money on ammo in training was superior to gadgets.

The 3-round burst on the M16A2 and M4 was a work-around to teaching the troops how to properly use the happy setting on the rifle.

I said, at the time, and I was a wee young waif then, "full auto is something you don't need in your service rifle very often, but when you need it, you NEED it."

The 3-round burst is an example of where you might NEED full auto, and ain't got it.

I notice it was dropped and all the M4's were converted to M4A1's with the SOCOM heavy barrel.  Really shoulda called that an M4A2.
