I almost forgot about this forum. So , how's everyone doing? 
Good Morning maamu! Long time no see. I hope you've been real productive during your absence here & capitalised on the situation in Paxtan to SIGNIFICANTLY increase your land holdings there since that seems to be the only asset of worth apart from gold in NAYA PAXTAN.
Moreover like all good ex / serving faujis & equally good Allah fearing Paxtanis hope you've thoroughly squeezed those desperate for cash in lieu of sale of land by forcing them to offer throwaway prices thru cartelization, then paying them in installments lasting yrs if not months .
Allah aapke is farakh dili par khud apna farakh dilli ata farmaaye aap par & aapke khaandaan par.
Suma ameen.
About the thread , this is the first ever participation of Thunder B , two seater in a foreign exercise.
So definitely more to it than just a trainer.
About the thread, rather intriguing selection of nations isn't it maamu? I mean Greece is in whereas Turkey should've been there or perhaps it was deliberate signalling by the Saudis here in which case what were the Qataris doing in those exercises ?
Seems to me from the odd grouping, the US & UK were as usual going to explain tactics with the Paxtanis there to learn & implement them for their masters whenever they're summoned by the latter whom Paxtanis also in an exaggerated sense of their self worth often refer to as Biradar mumaalik though in private the term of address is always AQA.
Goes without saying the Saudis may have paid your part of the contribution for participation in the exercise.
Finally good to hear the B series also doubles up as a Fighter Aircraft. Given the fact that every Blunder is a fourth of the Fighting Falcons in capabilities every addition counts, especially in these times. You can always train on a simulator. After all the Americans are doing so & given your present economic status, it'd come as no surprise to anyone if you exclusively practice & learn flying on simulators leaving the Blunder B to function exclusively as FAs.
Then there's the issue of your engines & the fact that both you & Russia are hard up for cash. We'd leave that for another day. Toodles Maamu & all the best for your land dealings in Paxtan sorry Naya PAXTAN.
