How can i detect a physics colision

Hi, collisions noob question.

I have a level which is a trigger mesh that will destroy bullets and decrease the health of the ship when touched.
I also have enemys which need to reduce health when they crash into the level.

^^This bit i can do with the trigger callback on the Level script.

Problem is:
Enemies and ships are both rigid bodies that collide with the level, but when they hit each other, how can i detect that to A) decrease their health and B) play a sound effect? If i turn the trigger on one of them then they pass through the level mesh.

Not all collisions can be detected. Take a look at the Collision action matrix in the documentation.

For example kinematic rigidbodies cannot collide with each other.
