A perspective from the inside
Sounds like the US Army. I'm posting anonymously because I know people who are still serving, though its getting to be a dwindling number and I don't want any of my friends taking shit because I'm a loudmouth. It happened enough when I was still serving.
I left almost two years ago as soon as I could take my retirement, I served as an Enlistedman and as a Warrant Officer in both the Active component and in the Army Reserve. Unless you have been in it, you have no concept of how it works. You may have a vague idea, but you don't know just how bad it really is. Some of you are talking out of your asses and have no concept of how things are. Some of you have been close, so I'm suspecting there's some experience here from people who were in a NATO Army; maybe the US Army, maybe the British Army, maybe the Canadian Army or the Bundeswehr's Heer but one of them. Especially accurate was whoever mentioned after hours work, it happens enough to Enlistedmen as it is, you have to serve a Staff Duty shift at least once a month and in most units its a hell of a lot more than that (For example Male Drill Sergeants at TRADOC have to do it at least once a week for two years and maybe three if you're good at it).
From my experience most of the people who are in a position to do something in regard to the shit with the Army's information Management infrastructure are Junior Enlisted and Non-Commissioned Officers with a very rare Warrant Officer around here and there who is a technical expert with precisely zero decision making power in practice. Especially when there's some smartass 23 year old 2LT or 28 year old Captain who thinks they know everything running the company, and they won't do a damned thing about it even though they know its fucked up because doing something not only means more work for them, it also makes some Commissioned Officer (who may very well be an extremely insecure and petty son of a bitch that holds grudges as long as God) in your chain look like they're not doing their job, and making someone who will most likely be sitting on your promotion board look bad is a dumb idea if you're planning on staying in longer than a "four year queer". Occasionally you'll get someone usually coming back to a CONUS garrison from a forward unit who doesn't fucking care and will try to do something to correct issues but that's pretty damned rare.
These same commissioned officers were branched into signal because they probably lacked the brains for engineering or intelligence and lacked the balls for combat arms but still did their five years at West Point or four years in ROTC and have to be employed somewhere for at least five years. This is why I got lucky in the units I was in, When I was Enlisted we were usually left alone by the Commissioned Officers to do our job the way our first lines (who were NCOs) wanted us to, and when I got my warrant, my commissioned officers listened to us and the NCOs. I wish that was common. It isn't outside of Combat Arms and SF (I was not SF, and I was not Combat Arms. I was just fucking lucky).
If they'd let the NCOs and Warrant Officers do their damned job without 2LT Pimplyfaced R. Shitforbrains and CPT Mouthbreather W. Point IV countermanding nearly every decent decision that gets made further down because they don't like Sergeant Sierra and CW3 Hotel because they won't kiss their asses and constantly tell them how great they are, it wouldn't be that bad but it rarely happens.
The only good thing about ARCYBER taking more responsibility is that MI might finally get to make more real decisions regarding security aside from telling TRADOC what to put in the FMs, TTPs and TCs that never get read outside of AIT and PME, but I doubt signal will ever let that happen. Look at how long the UAS programs lasted inside of MI, Aviation felt threatened and INSCOM caved because MI has no balls.
