You should read C.J. Chiver’s ‘The Gun’. The M16 was absolutely not ready for deployment in Vietnam, and the military’s initial stubborn refusal to issue cleaning kits for the ‘self-cleaning’ rifle cost many American lives.
My point was that Ennis blames the corporation in his (not) M16 tale, when it was the military itself that fucked up, first by pushing the "sharpshooter" idea and stubbornly refusing to acknowledge the realities of modern warfare, making procurement of the M16 an urgent need, and then not issuing cleaning kits, not training the troops and most damning of all, issuing the wrong type of ammo.
We can point the finger at Colt for cutting some corners (i.e. not chroming the barrels) and glazing their product a bit too much, but it was ultimately the military that fucked over their own troops, and not just with the M16, but in a myriad of other ways.
Moreover, you need to look at the larger context. Vought’s failures in military hardware
I really don't, because Ennis is mentally a child, with a "capitalism bad!" axe to grind, and is also too lazy to do the bare minimum research.
I can't take Vought as an antagonist seriously because they read like a parody, but Ennis is too stupid to realize this and thinks he's shitting out some scathing social commentary.
and the CIA is counting on The Boys to keep it from happening
Which is fucking hilarious, because, while the rest of the US government is negligent and apathetic at best, the CIA is actively malicious.
If the Boys had any connection to reality it would the CIA pushing for capes to become the premier weapon platform of the US government, both because they are arrogant enough to believe they could control them, and also because they'd want to take the military down a few pegs.
