could be a printing mistake, or maybe something is coming ... but my best bet would Pantsir S1/S2 at most .. there is no way Russians will sell S-400 to Pakistan for now, if they did .. than i would call it a big step towards a close more strategic relations between Russia and Pakistan ..
@TheOccupiedKashmir the requirement for LR-SAM was put in cold storage for sometime wasn't it ? when we inducted the HQ-16 most likely 8-9 Batteries is already in service, i think PA will be looking to cover more Air Space with a MR-Sam , but if the requirement for LR-SAM is given a new life, and Russians some how get into the fold to put their product than i cant help but to even consider that maybe S-400 is been offered to PA on a very slight note .
