The military ops at civil fields do not normally constitute a significantly heightened risk to users. A break is an efficient manner to enter a pattern, and for a fast mover mixing with slower traffic, it actually increases the likelihood of target acquisition, a C-152 is going to be a small radius of threat vector to the fast mover, whereas it can be all aspects to the slower traffic. A low pitch height places target traffic above the horizon, increasing the probability of visual acquisition. the low pitch climbs the aircraft above light traffic, but enters the jet traffic height, except for FLCP, where the plane is down in the weeds and waders.
More concerned flying low speed aircraft into uncontrolled airspace, other than choppers... choppers just make things simple for chopper pilots which is appreciated.
