The idea of this being the 29 Baloch BAT team seems incorrect reporting, it is more likely the 19th SSG Baloch battalion with one of its BAT. I think a bit of patience is also required, an immediate response is silly. Guys from the same platoon will finally avenge their brothers. Time for this platoon to pay for its actions. A covert silent op is far better. Recover the head if possible and the pigs, return the bodies of the pigs the next day in public. killing the whole SSG platoon should a fitting response for now and leave the further escalation to them. I think the entire 13 men team + platoon needs to be taken out. Shoudn't be hard, a few UAV sweeps, we know which posts they came from, so track and trace, perhaps a sudden brazen attack against all the posts in the area + specifically target the particular group.
Its easy to have a mortar or artillery strike, however, I would rather they die in the hands of our professionals. However, we should arrange for their bodies to brought back. All the bodies with unfiroms to be paraded the next day.
There are about 3 or so posts over there we need to have precise intel on who those SSG pigs were shouldn't be hard since the injured can ID them using border survaillance techniques + equipment. Detroying them would take less than a few seconds http://en.wikipedia.org/wiki/RPO-A_Shmel
3 to 4 bumblebee shots would ensure all those posts are taken out in seconds, our units can move in, kill, snatch and grab, a well planned lightning fast attack. Have a company as back up in the area in case they want to escalate after the mission.
