Canada's UN Mission twitted a letter from the Russian UN Mission that was sent to all member countries.  Canada's UN Mission decided to troll hard the letter by marking it up and returning to the Russian UN Mission.
 

I translated a document explaining FAC procedures a while ago, perhaps this might be interesting as well?

According to this, specific entities might be given a callsign in aviation, typically the brigade combat management group (HAT [kaska] in this case) and the actual forward controller (VOLLEY-21 [zalp-21] in this case).  The aircraft is given the numeric callsign, however.

Manual is in russian, I think you can skip through google translit.  😃

For most line units during the soviet era it was pretty much completely numeric IIRC. 
It depended on the commander of the higher unit, but the numbers on the side of the vehicles were the callsign for that squad + vehicle (especially because the squad's radio was the vehicle). 
One way I've seen it was XYZ, where X was the battalion number, Y the company in the battalion, and Z the squad/vehicle in the company.
So 346 would be 3rd battalion, 4th company, 6th squad/vehicle. Soviet companies were usually 10 strong, with XX0  being the company commander, XX1 through XX3 1st platoon, XX4 through XX6 2nd platoon, XX7 through XX9 third platoon. The 1, 4, and 7 callsigns would be the platoon leaders for their platoons.
Because the vehicles were their main radio source, I believe most units simply stayed and communicated on their respective company net. 

I have to say that I started watching this with some skepticism.. but I have to admit that I was surprised at how much I liked it.  Episode 3 in particular was outstanding.. but that last episode...  wow.  If you haven't read the book (and I had not) you will be taken by surprise at the way it finishes.
Well done.. even though I had some issues with some of the art decisions, overall it really is a beautiful show and well worth watching.

Poor quality German troops caught up in Market Garden buzz-saw.
They were flanked by Brit Para Recce forces in Vickers mounted jeeps. But most of this damage was done by the trusty 2inch mortars.

Baa Baa Black Sheep of Brothers 

Based on Alex Kershaw's book about his experiences as a company commander from up through the Italian "Boot" (including Anzio), Southern France and into Germany with the 157th regiment.
Was a really good read. The movie looks like it has added an entire dramatization that was absent in the book. The whole "dirty dozen/band of brothers" angle has been manufactured.
Still, if it stays mostly true to the book it should be a compelling visualization.
