Well put there Boatmanshcneider. After serving in multiple deployments since DesertStorm to present day, and on the brink of another one soon, I agree that a select fire rifle has it's place in the current arsenal. I would rather do away with the 3 shot burst, and have the ability for my Infantry platoon rifleman to have the option of fully automatic fire, but since I'm just a simple grunt.....all I can do is to "recomend" this.
Room clearing seems to be the current topic for the need to have full automatic capability for rifles, but there are other reasons for this as well. Boatmanshcneider has covered a few for link fed/crew served weapons of a typical rifle squad, but an example of times when a full automatic capable rifle would serve a good purpose is for the M20B assistant gunner if the M240 has a stoppage (It can and has happened at the worst times in life)....or when the M240 is in need of some more ammo, or a bbl change. The AG can pick up the fires temporaily whilst the gunner gets his hog back in buisness.
Just one example, and part of this specific issue can be addressed by using the "talking guns" techniuqe, if multiple M240's, and M249's can be utiliezed on or along the same axis of fires.
One other thing that I didnt notice mentioned was ROE (rules of engagement)
This comes down from "higher", and is to be followed...period. The more strict the ROE is, the more limits are put on the "end users" for the .."what can we use", and "how we are gonna use it", so to speak. ( Example: The use of handgrenades, in paticular...concussion/flash bangs... to "prep" a room prior to clearing it is in most cases...safer for the assaulting elemnet, but...the ROE might prevent it's use.
In short..... thier is a difference between dynamic, and precision room clearing. IMO..... the ability for that young E5 (team leader) to have rifles with fully automatic capability will give him more flexibility when he needs it, and as an organic asset that he can control. Like I mentioned before...... I can only recomend as I'm a senior NCO. Either way, we will execute any given mission with whatever congress wants us to use. I cant speak for every branch, nor every Infantry unit in the Army, but you can rest easy...as your tax dollars are being well spent in mine.
