There's a comment on UA Weapons or Oryx that the two tanks are new, the M113 has been there a while (apparently since January).
I saw a longish youtube of some UKR TD guys defending that crossroads a few days ago and the M113 is there. Found the clip, can see the M113 at 10 minutes if it doesn't go there automatically. The whole time I was watching this I was thinking/saying - "Guys, get behind some cover FFS". The russians are just down the road to the left as they approach the M113. You can see the incoming fire hitting the building next to the 113 and one of the TD men gets hit.
