Still lot to read but I have questions.
I see that there's a School-Unit Group which was subordinated to I. Army HQ. and was basically a division level unit, a model one, properly equipped. Did this serve as actual training unit and the crew was rotated? Liek conscripts were assigned to this unit for a while after base training, but then moved to their final unit? Or this was just a name?
And there's the Academy, or more properly the Agulhas Negras Military Academy where commissioned officers of the Brazilian army are trained. Now, you wrote here >>39510
>It bears noting that he and the two battery commanders studied at the Academy.
Which means others didn't. Were those non-commissioned officers, or other higher education facilities for the military exist?
