Lusaka Tower, this is Green Leader. This is a message for the station commander at Mumba from the Rhodesian Air Force. We are attacking the terrorist base at Westlands farm at this time. This attack is against Rhodesian dissidents and not against Zambia. Rhodesia has no quarrel, repeat, no quarrel, with Zambia or her security forces. We therefore ask you not to intervene or oppose our attack. However, we are orbiting your airfield at this time and are under orders to shoot down any Zambian Air Force aircraft which does not comply with this request and attempts to take off. Did you copy all that?
Yeah, since I like all of you, here's some images which might help you make your own insignia/heraldry/other badgy stuff. More coming soon. Note these are categorised into SVG/PNG format
