I don't want to get overly involved in these Ebola threads, as they seem to be full of insane paranoid fiction, out-weighing the occasionally intelligent comments. The medical professionals always have to deal with fear and nuttiness.

Military disaster response folks--medical, firefighters, and police--routinely (as in "required by regulation") engage in mass casualty/disaster response exercises with their civilian counterparts. (Can you say "FEMA"?)

This isn't about a "military takeover", it's about the military being designed to pack up and go anywhere, and coordinate between different organizations. It's about the military continuously training for biological warfare agent decontamination and treatment and having field hospitals that can be deployed and set up quickly, some of which DO have the capability of positive pressure isolation/quarantine.

It's also likely that, for a team such as that described, those on it did volunteer, and are also highly qualified.
