The other thing to understand is, this may be something his wife wants more than he does.
Unfortunately in relationships, after both parents have made a decision (and sometimes one parent might not have wanted it, but agreed to it because it wasn’t their highest priority and they wanted to avoid a fight), it’s still that parents job to communicate that decision to their side of the family.
But I had a similar situation to you and you brother, and similarly my dad made us play outside basically whenever it was nice outside, so your correct that regardless of what tech a kid has, ultimately parents decide how to use it.
But it may also be that they know their kid well enough that they know the restricting of that tech will cause more tantrums/problems then giving it in the first place.
Parents have lots of strange rules not rooted in logic or reason unfortunately, it’s part of the insane crazy love we feel for our children. All you can do is what you’ve done, say your piece and move on.
Not military but my understanding is:
Commissioned officer: starts at second lieutenant, can go all the way to lieutenant general, have to go to specialized school (like West Point) to be eligible. Receive their “commission”/assignment directly from president. As the other commenter mentioned, BG is fairly high up.
Each service can have slightly different names for certain positions. And yes they split CO positions into three types, company, field and general, BG is the lowest “general officer”. As to how, you could always ask, but some combination of seniority/achievements. He almost certainly serviced in combat in Afghanistan/iraq as a field officer given the timelines.
Non-commissioned officer: these people joined as rank and file, and got promoted to oversee/command people below them, but didn’t go to specialized school, and can’t rise above sergeant major. So you could have a guy with 20 years of experience commanded by a brand new second lieutenant.
Rank and file: privates and the like.
