If I was going to ban all aircraft used by the military then there probably wouldn't be any aircraft that would qualify for this comp what is no allowed is aircraft specifically designed for military purposes the L-188 is fine but its military version the P-3 is not acceptable like the Beech King Air B200 used by the RNZAF is acceptable but not in the military colours.
The de Havilland DH.104 Dove is acceptable but not DH.104 Devon which is the military version.
Mike the CL-215 was designed as a civilian aircraft as a water bomber which is acceptable but the one you have entered is a Hellenic or Greece Air Force - Canadair CL-215 Scooper with the blue white blue markings on the tail and the Hellenic air force roundel on the fuselage.
Non Military aircraft means just that, to put it in a nutshell no aircraft specifically designed for military purposes you can use all prop or turbo-prop multi engine civilian aircraft except civilian aircraft painted in military colours.
Now I hope that is as clear as mud and no doubt will confuse you all a lot more
