Jordanian-Pakistani military relations is very strong ,Through history Pakistan stood by Jordan during the wars, and so did Jordan During the Pakistani-Indian war, There are military courses and joint exercises on a regular basis between the two countrys, My uncle served in the Jordanian Arab Army until he reached rank of lieutenant colonel, He always talking about military courses in which he participated in Pakistan, If your question is about the possibility of employment in the Jordanian Arab Army as the case in the Saudi army, This is not allowed because there are large numbers of Jordanians want to join military service, Thank you my brother and I wish you all the best
