I wonder if this is the 40th Kryvbas Battalion. The thing about these “Territorial Battalions” is that there are 50 of them numbering 7000 men in total. That’s 140 men per battalion, or roughly what we’d call a company. The terminology is all over the map. Back in the day, an NVA regiment was 500 men.

Likely one and the same...
A couple of officers from it had been tweeting for months, and suddenly went dark about a week ago.
