Well first thing is that any new units of Jfs seem to always stay at Kamra for a while, especially if its a new mod vis first Blk 1 then Blk 2 then B, so obviosly Sharpshooter being the first full unit with Bs was destined to move out to make room for the first sqd of Blk 3s (remour has its the Tigers).
What Im surprised is No. 18 Sharpshooters moving to Bholari instead of Mianwali. Granted it was F-7s OCU that was at Mianwali but since those types are now nearly done and dusted (if you include PGs as well), then it would make sense to have the F-7's OCU homebase to house atleast some Jf OCUs. All this suggests PAF is taking LIFT very seriously and that will be Mianwali's role for the foreseable future.
@Windjammer what makes you think its not a Blackpanther piece? Even non-OCU sqds were supposed to receive one or two Bs (source: Interview of PAF person in some magazine, cant remember where).
