Traveller/Awesome

Traveller is full of interesting CMoAs written into the sourcebooks. Here are some of them.
 * Merchant Prince Marc Oberlindes contrives to buy a large ship from the Imperial government and recommission her as a freighter for traveling in Vargr territory. As this area is full of Space Pirates Oberlindes somehow arranges for the Imperial government to "forget" that there is still military grade weaponry on it. With this the ship, now named the Emissary, sails right through hordes of pirates, laughing all the way.
 * At another time, Marc Oberlinde's son, Sergai, is held captive. Marc recruits a band of mercenaries to rescue him.
 * The Battleship Gram, a transport containing several divisions of soldiers and a few smaller ships are trapped when they hear the Earth government they were fighting for had been overthrown. In response they sail all the way through Aslan territory to found the Sword Worlds.
 * In Alien Races 4 a Bwap, a member of a race famous for its enthusiasm for bureaucracy, stops a mother with a baby in a line of tourists by claiming her ID was faulty. This causes a jam-up in the line behind her and diverts considerable attention, not to mention wrath. While everyone is busy arguing with the Bwap, Imperial police snipers sneak up on some terrorists in the line and catch them. Later the Bwap gives the mother part of his reward as recompense for the unwitting part she played in his Batman Gambit.
 * The whole Intersteller Wars; Planet Terra taking over the entire Vilani Imperium.
 * In another instance they are hampered in an expedition by Vargr Space Pirates. So they buy a surplus Imperial 60,000 ton "cruiser" allegedly for salvage... and then bribe and manipulate several Imperial officials to have it 'accidentally' delivered fully intact and with weapons still mounted. They then immediately move it outside Imperial space so they cannot be charged with illegally owning a warship under Imperial law, give it the rather ironic name of Emissary, and send it through Vargr space, sneering at every corsair in the galaxy.
