Note also that MARSA may be in use on low level training routes and
MOAs and that a military controlling facility that may be using MARSA
may not be able to communicate with civilian aircraft.

In those cases where they are unable to communicate with civilian
aircraft, how does the military assume responsibility for separation
of aircraft? Do they relay communications through FAA ATC?

Also there are both IFR and VFR low level training routes and procedures
differ for each.

I presume, no separation is provided for flights on low-level IFR
MTRs, while it is provided, or the military takes responsibility for
separation, on IFR MTRs.
