If you need shields call DU/CG, aswell as the restraints, call CG.
You join medics to be medics, having the title of hazard trooper makes you a hazard professional and you should state that when handling things the Hazard troopers would do. Remember, RM have authority over Medbay, if people don't like that they can be the grumpy grumps then because you can of course, call CG.
I understand that you want to have unique things for each class but by having these it would make CG/DU less special is what they do. DU is specialized for their shields, CG is special for their speed boost and hand restraints (and the riot trooper of course has a shield).
Also for the passive RP aspect, the hazard trooper calling CG/DU to handle these situations would promote passive RP with people outside of just the RM, of course don't be a minge about the passive RP though, and if DU or CG is being a minge about the passive RP bit then you can report it to a CO.
