Intense combat by multiple brigades
This video claims to show multiple brigades operating together. While it's not clear where the first half of the video is taken, it is clear that the second part of the video is actually taken from inside the base, perhaps further east than some of the other videos. Note the radar towers, the AA machinegun hills (which also serve as very effective anti-infantry weapons).
