Myf controller described a near midair collision between myf pattern traffic and a nkx military aircraft; the reporter noting this type of event is not infrequent and suggested more information be made available to nkx itinerant operators.

Narrative:
I was providing [on the job training] to a developmental on local control. The controller lost the picture and I took over with moderate traffic and complexity. In the midst of the situation I was alerted by the ground control that there was traffic in our airspace. I observed a military aircraft opposite direction to my departures and parallel to my downwind overflying at roughly pattern altitude. I saw that it was on a direct course to blindside one of my pattern aircraft so I issued traffic. I don't recall if he acknowledged; so I issued it again. I watched as the military aircraft converged and overflew very slightly ahead of the cessna. I issued wake turbulence cautions as well. It was one of the closest near midair collision's I've ever seen. This frequently happens with itinerant aircraft into nkx; but they are usually much closer to nkx. This is the first time I've had one actually in my pattern; at pattern altitude. They are usually above it. There needs to be a prominent notice in the AFD advising the military pilots into nkx about the danger of swinging wide into the myf pattern.
