Just read an article that documents that when trained professionals (& the rest of us) fire under stress we lose our fine motor skills. This accounts for the very poor accuracy experienced by ALL shooters and it is unavoidable regardless of previous experience or training. This being the case, other than for snipers, why bother with the extra expense for a more accurate combat rifle like the M16 oe M14? Seems to me that an "expert" at the target range would be hard pressed to make "marksman" in the field when the shooting starts. I guess spraying with the "cheap" AK makes sense.
