Halo 4 secialisation not working

I just got to level 50 and have chosen tracker for my specialisation. when i get an ordinance, there is no option to change ordinance selection. Do i have to wear the specialisation armor or is there something wrong here that i have to wait another 10 levels to get another. Can someone please explain whats going on? Thanks

You unlock the Requisition mod (which allows you to change your ordnance) after you have fully completed the specialization. In other words, you unlock it at SR-60 and must equip it to your loadouts in order to use it! :slight_smile:
