Does the Army infantry squad need to be reorganized?

I've been out of the infantry for 2 years now but size wise no. A 9 man squad is sufficient. If anything, I think more units should focus on small unit training/ SGT's time training. I received a vast amount of training and knowledge from SGT's training. And that's when I was in a 11B capacity. I was a Chuck and did 11B work from time to time including my second deployment. Technology is ever evolving, and I believe with our Army's vision for future conflicts will bring about better technology and tactics for the infantry.

I remember back in the day when I was in we had 11 man rifle squads, 1 SL 2 TLs, 2 grenadiers, 2 Autorifles and 4 riflemen. Weapons Squad had 1 SL and 3 MG teams of 3 men each. PLT HQ was 1 PL, 1 PSG, 1 RTO and attached medic. Never really had that many due to casualties, details such as KP, R&R, etc. Often no PSG, not a current rank, with a SSG or SGT acting as such, same same for the LT.

I believe they are going to change the organization of an Infantry Bn and BDE based on former SecDef Mattis desire to make Infantry squads more lethal. That is if they are still following his mandates. One item I read in another RP article is reintroduction of the Stinger ADA in each Mech Infantry formation at least at the BN level, possibly further down. I personally feel as former Cold War era Infantryman you guys need more conventional warfare training. The insurgency training you got as part of GWOT was probably good but it should no longer dominate now that those wars are ending. There should be more of a balance now as there was prior to GWOT.
