Essentially, I propose the addition of a ERT response room on the CentCom Z-level. It would be in the same area as the Death Squad shuttle. Essentially there would be a bunch of useful equipment dividing into three roles, Medical, Engineering and Security of which there is only enough for two roles each. Admins would need to manually spawn in players to the room to suit up. There would be around six operatives.
The ERT would essentially function as a way for admins to attempt to save a station that has not yet reached the point of blowing up, as well as getting some players back into the round. They are not meant to wipe out a Xenomorph infestation, they are here to help people and not kill everything. Their armour and equipment is robust and above average, but not even on par with the Deathsquad.
The roles would function as follows:
Engineering: Has tools designed to quickly and efficiently fix damage.
*EDIT* I could possibly set up a system to allow admins to spawn in a ERT akin to spawning in a antag from the 'Spawn Antags' menu. That would work well.
