No they did not go anywhere, they were part of the operation the whole time. PMF forces were all there and liberated the Tiktrit with Iraqi army. They were the ones who did 80% of the job (capturing 90% of the landmass around Tikrit and putting it under a siege). The only reason why city was liberated so easily was that most of Daesh terrorists had fled the city before the siege was complete. They didn't go anywhere to come back and rumors that they had left the operation came out as total rubbish.
And no, Jordan is not doing shit in the bigger picture, of course except that it destroys 20% of IS each day in a ground shaking response by his majesty, British Abdullah.
PS: The only reaons that you (and your likes) are more focused on spreading bs against Iraqi forces/PMF rather than fighting Daesh is butthurtness, I can't see anything else. After all, you were the same who cheered for Daesh (the same for Nusra) when it began its crusade in Syria. I remember those days, and members should know your history.
