Jason St John is pretty legit. At least he definitely used to be.
I can see both sides. There is an undeniable "joe" factor that will apply abuse to a piece of equipment that no down select or operator testing can accurately proof. The more poorly trained the user, the more abuse that equipment is going to experience. Joes will cram as many rifles as they can in a tough box, a trained operator will carry his NODs, radio, and pistol in a well padded 1750. Some people call the SF E7 " the most highly paid rifleman in the US Army" as a derogatory term but that selective training and experience does get you something.
I remember the propaganda of "the massive rate of failures" of the M4 coming out in 2005'ish. Quotes from Rangers in the account of QRF'ing at Roberts Ridge. "I got off the helicopter as we were taking fire and returned fire with two rounds and my rifle jammed. I pulled out a cleaning rod I carried for just this issue and cleared the rifle...". I remember reading that in a article that was making the case for the 416. There was a flurry of that stuff for a year or two before fading away. I remember reading that and being amazed at how my experience with the M4 was nothing even remotely close.
I do agree that we need to develop the next generation of weapon systems. Every major state is innovating at a rapid pace. If we think we're just going to stick with the M4 for the next 20 years we're going to be in a state of panic one day and forced to whip out some serious garbage in a reactionary emergency. Right now is not a time to stick your head in the sand when it comes to keeping up with the Joneses. I won't say the current process and cost of how we do that is perfect but it's not like there's a long line of really good credible, privately well funded companies generating the perfect rifle ready to hand it to DOD for free. I really don't have an extreme opinion of SIG one way or the other that people on this site seem to. I don't own a single gun of theirs. But I think they need to iterate in order to develop. When you read St Johns comments, he's absolutely right. Even if we decide to move away from a large frame platform and cartridge and have to start over, DOD needs to learn that lesson. Like a lot of things, success comes from learning from failure.
I wouldn't condemn either side and I also wouldn't get your panties in a wad over teething issues and a series of iterative improvements.
As far as a BN CSM writing a white or information paper, LMAO. Ain't no line BN CSM writing a report. Dudes got 99 problems but he ain't writing papers. And if he did, guess who he would use to do it? A CPT. AKA the " MK 1 MOD III prod generator".
