General K.M Arif(VCOAS and man behind Pak response to Brasstacks) writes in his book, Khaki Shadows that GoP had authorised the raising of a new Corps HQs for Offensive operations. The new Corps would've been compromised of 1st Armd div and 7ID. But when the file was presented before Musa Khan, he rejected if saying:
We don't want another lieutenant general to be lurking around in the GHQ" !
This means that there were no budgetary constraints as far as this issue is concerned.
Imagine if there was a corps hq to handle the ops in Khem kharan, almost all of the reasons (on PA's side) for the debacle would've been brushed aside...
