I've been trying to understand the geography in the sector where the current situation has developed. And make sense of disparate news items appearing in the media.
Here is a snapshot of the area:
Couple of observations -
1. The geography is pretty challenging in the area with steep mountains and nullahs. The area is heavily forested and gradient is very steep.
2. The SOP in the area seems to be to control the ridge line(s) - the picture shows what seems like Company HQ and closer examination of the area shows tracks leading from Company HQ to forward slopes.
3. There are tracks leading to rear slopes and rear-areas - in fact, if people had been paying attention to news footage, one could have made out troops moving up mountain slopes on clearly marked and wide tracks. I don't know whether smaller vehicles like Jeeps can move up these tracks.
4. There are east-west nullahs between these ridge lines - I could not make out any IA posts or any such infrastructure along these nullahs. It is these nullahs which serve as the main infiltration route(s). I think IA sends out patrols and lays ambushes along these nullahs to prevent infiltration.
5. Plus, we have the fence in the rear areas to serve as filter and additional challenge.
6. From military perspective, holding Sala Bhata makes no sense - it is situated on forward slope at a much lower elevation as compared to area around it. It would be under direct supervision of PA posts on higher slopes ahead of it.
7. Setting a 3-side cordon itself would be a challenge - two sides have steep mountain slopes and one open towards the nullahs. While theoretically, you can fire from higher elevation towards the nullahs, the steep slope and heavy forest covers screws such calculations. Plus, you've the PA from opposing slopes across the LOC keeping a watch on you and firing at you to pin you down.
8. Further, I think Sala-Bhata is being used in a general sense - the militants are hiding in the general area taking advantage of the geography and the fact that they have line of communication from PA side.
