A few years ago, when things were tuff getting ANG personnel, I heard plans were in the works to recruit traditional Guardsmen into hard to fill billets from a pool of AD retires. The deal was you kept your AD retirement, but on drill week ends or any TDY, you would loose that days retirement pay for a day of active duty pay. Some how the accountants would be able to keep up with all this. I never heard if anyone has done this.
