Instead of excusing bad soldiering from war to war because of MOS and getting defensive because another branch doesn't have these basic problems, address it honestly. Civilians are clueless because you soldiers deliver them rediculous excuses for failure. An entire unit of soldiers were useless because all of them shared the same weapons failure and you seek any excuse other than your branch and those individuals. It shouldn't be about defending your problems. It should be about fixing them so that future soldiers don't keep making the same simple stupid mistakes.
Moot is seeking any desperate news article out there to deliver an excuse that no other convoy acrtoss the branches shared. You offer up their MOS as an excuse for bad soldiering. Moot offers up CLP as an excuse for bad soldiering. She also offers up that the weapons were in the back of the vehicles and not even on their person as if this makes it any better. Hell, we even want to entertain that none of them remembered to chamber a round. Is this how far we are going to go to pat their heads? In the end, no excuse exhonerates the truth, which is that this is an institutional Army problem and an individual ineptness to basic soldiering.
Like I stated, the moment a convoy of admin Marines or supply Marines gets caught with none of their weapons able to fire or their weapons not at the ready you can start seeking a more complex theory. Until it happens, this is a problem confined to your branch. Running from it encourages the next convoy blunder.
