Dear Taimikhan
Whereas you are right on the mark in respect of infantry fighting formations in a division; “”Brigade = 3units = 800*3= 2400 approx
One Div = 3 Brigades = 3*2400 = 7200 approx””
Your description of TO&E of a division is obviously flawed. During active operations, Organizational and support elements are actually higher in number than the fighting formations. They include:
 Headquarter / Staff elements
 Artillery
 Armor
 Signals
 Air Defense
 Reconnaissance
 Logistics & Supply
 Medical Services
 Combat Engineers
Therefore your average full strength division is not 7200, but close to about 14-15,000.
In war time the headquarter & staff members are not at full strength as many of the officers are sent to their parent units or wherever required to boost the officer strength in the unit. Only necessary & critical staff is left. Artillery is already there, around 2 -3 regiments & they are not placed at one place, scattered around different bases. Armor is there but not in full strength as a typical army unit when fighting on the eastern front, also around 80+ tanks have been provided to the FC too. Air Defense isn't there as this is COIn not a conventional war, signals guys are attached in company sized not full strength. There are no reconnaissance troops, as this task is done by the troops already involved in operations or in the units in their operating sectors. Medical Services are also in few hundreds as no full fledged military hospitals there, critical wounded are air lifted to nearby main garrisons. Same case with the rest of the arms as this is no eastern border. Plus, if you read my post i did mentioned few thousands to be added for support arms in these divisions, i guess you missed that part. In no way your division has 14000-15000 troops as it will make the support arms number equal to the fighting formations or near to that.
South Waziristan operation underway amid curfew
DAWN: Saturday, 17 Oct, 2009
“”The official said three divisions of the military, paramilitary and police would be mobilised, eventually numbering up to 60,000 troops, to spearhead a lightning campaign before winter set in””.
And sometimes the divisions are not up to full strength of 3 brigades, even brigades are not with full 3 units, this is based on operational requirements. They are using the word "eventually", which i believe they mean to say in future, not right now.
In addition you have to consider the following factors:
1. How long can you keep the combat formations in the self created “war zone”? You got to rotate them? You got to have reserves.
2. Some formations will go under strength due to casualties and combat losses.
3. These are Aviation intensive operations. The workhorse is MI-17. Due to excessive abuse during Swat operations we have run out of spares and most airframes are due to overhaul. Recently the US Army transferred two (2) Afghan Army MI-17’s to absorb the crushing burden.
In simple words Pakistan Army has no choice but to move fighting formations and support elements (especially aviation) from the Indian border.
This is a serious vulnerability, because in the event of tensions on the Eastern Border PA does not have the flexibility to move the FATA deployed troops. We are no more as “India Centric” as we wish to call it. In simple words we have “lost” the equivalent of about eight (8) divisions!
The normal tenure of operational tenure of any unit in such COIN situation is around 1 year, can be extended by any other 6 months too. Plus army has its own system of rotating the units when their operational tenures are over ranging from 1 years to 3 years depending on the station posted. There are some units who are stationed at the same station for over a decade due to their operational capability. Army does not have reserves for such things, the units who have completed their tenures at peace time stations are sent to replace the units who have fought & done with their time.
The reserve brigades with each division deployed in SWA is for the reason that in case a units gets reduced in numbers, they can be helped with the units in reserve formations, plus as per my information, in one incident most of the officers of a unit where injured in one big operation, that unit was then put administratively & operationally under the command of another unit, till their officers did not returned to active status.
Do you think PA is that stupid to be using all of their spares, even the war reserves on such small operations ?? Or stupid enough to have used all of their Mi-17s at the same time ?? Come on yaar itnaa bhi stupid & underestimate naa karo PA ko. As for Aviation, PA has expanded the fleet considerably, it was at one time short of experienced pilots, the unit in which my bro is serving saw 4 officers leaving for aviation in less then 2 years time, while in the units 40 years existence only 1 officer had been selected before. So as the aviation has expanded, they have utilized the expansion by efficient deployment & have not compromised the fleet assigned for eastern borders. Just see how many news helicopters we have gotten, around 25 412s, all 25 Pumas operational, additional super pumas from UAE, more Mi-17s, Fennecs, AW-139 coming, more then 20 Cobras. So kindly don't go on the press reports as they are meant for pressurizing the Americans to keep the flow coming so that we don't have to touch our war reserves.
If you remember in 2001 crises, the whole army was nearly mobilized in 2 weeks time, even the far flung formations of Quetta & Peshawar reached the borders. Plus, for deploying to Indian border, most of the formations have been taken out from Punjab based reserve formations & they are very near to Punjab border & in no time can be redeployed to their operational areas. 1 week at the max. Plus out of 550,000 army, if around 30,000 have been assigned here won't make any issue at the eastern border as 450,000+ are still there & the rest can come to the eastern border in no time. All your armor units still there.
I find it very ironic, that all the world, the US keeps crying that PA is still India centric & are not letting formations at eastern border move to COIN operations area & its elite formations are still facing India & that PA is buying weapons to counter India not the militants, how you come up to a contrary conclusion is hard to understand, the US has better satellite information then we ordinary guys to know what PA has deployed & what not.
Also, i don't understand why are you adding the number of FC guys among the 8 divisions total figure as they are not part of regular army.
Anyway, if you still wanna keep that PA has lost its focus on eastern border, your choice.
