The state is urging Ohio veterans who served during the first Gulf war to apply for a bonus before a year-end deadline. Veterans of the Persian Gulf War that ran Aug. 2, 1990 to March 3, 1991, are eligible for a one-time state bonus of up to $1,000. Vets who served anywhere else in the world during that time are eligible for a bonus of up to $500. Family members of veterans killed in action during the Gulf War are eligible for bonuses of up to $6,500. Voters approved the Ohio Veterans Bonus four years ago, resuming a tradition dating to the Civil War of rewarding state vets' service.
