Wilf, thanks for your new article. I found there also this article.

The Real Role of Small Arms in Combat.

Dr Jim Storr said:

To conclude, small arms fire kills and incapacitates very few
people in a typical infantry battle. The location and identity
of those individuals is critical to the outcome. However, the
effect of small arms fire in suppressing the enemy is probably
more important. Suppression fixes the enemy to enable
movement, or for elimination by other weapons. Suppression
is critically important, but also generally very poorly done.
I have to admit that my English is not very good, but does this mean that you have to send metal pieces towards opponent that make him find cover. This makes him slow and your faster guys just catch the slower one. Caliber doesn't matter? This reminds me that Wilf pushed somewhere also HK new small ammo. Wilf any comment, please?
