​This study examines the political role of retired military and security personnel in Jordan's legislative arena, focusing on their participation in the House of Representatives from 1989 to 2024. It highlights the structural and conjunctural factors that facilitated their growing presence, particularly during key political moments such as the post-Arab Spring period. The analysis explores the legislative and oversight behaviour of ex-military MPs, including their voting patterns on constitutional amendments, and motions of confidence, as well as their use of parliamentary tools such as questions and interpellations. The findings reveal a disproportionate level of representation relative to their electoral support, indicating shifts in the political landscape. The study argues that the regime pursued policies of co-optation and incorporation, especially in response to emerging opposition within this group. Their parliamentary presence has been instrumental in consolidating regime authority, legitimizing pro-government policies, and limiting executive oversight, thereby reinforcing the stability of the ruling order.​
