Green Lantern, Vol. 2

"Sonar's Sonic-Atomic Attack" - Sonar has managed to obtain diplomatic immunity, and uses that to gain American jet aircraft. Hal Jordan is one of the pilots assigned to train Modora's pilots, and he sticks around as Green Lantern to learn more if he can. He soon discovers the real reason Sonar wanted the planes, but he may be powerless to stop it.

"Tales of the Green Lantern Corps: The Trial of Arkkis Chummuck - Indictment" - Arkkis Chummuck was a lowly records keeper on his world, frowned upon as a non-combatant. Still, he had access to information, which proved to be a better weapon than any expected.
