According to this sorely outdated website that looks like its from the 90s........there are no AGR jobs period. But there are a few technician jobs. Note, that these types of full time positions require you to also have an obligation with a drilling unit.
You should check back as often as practicable to keep abreast of when new jobs become open. Aircraft mechanic positions are all dual status technician positions.
I agree. MOS slots can change over night and differ between states. Your best resource to use is a recruiter. When you are ready to enlist in the National Guard, you can either call the 1-800-GO-GUARD number or fill our the Pre-Qualification form: bit.ly/JMCld5.
