When Jamming is employed by.. let’s say the military against another military …the Group doing the jamming…how does their own signals not get jammed as well?

You jam specific frequencies.

The military doing the jamming wouldn’t jam their own frequencies as they know what frequencies they are using.

A few options. The most fun being:

1) Frequency hopping:

Say you have frequencies 1, 3, 5, 7, and 9 that you are jamming. You’ll jam 1, 5, 7 and 9 while transmitting on 3, then, the jammer will stop jamming 5 and start jamming 3, at the exact same time your transmitter stops transmitting on 3 and starts transmitting on 5. This presumably happens multiple times per second, so unless you are also in sync with the frequency hop, you’re getting jammed.

2) Alternate communication channels/types. For instance, jamming cell signals while using satellite to communicate.

3) Directional antennas can be used to create a “cone of silence” which jams signals in specific area/direction, rather than in a circle with the jammer at the center.

You’re trying to talk to somebody. I come near you and shout as hard as I can. I shout so hard that you two can’t hear each other. This is simply how jamming works.

This doesn’t stop me from talking to somebody else by written communication.
