I'm wondering if anyone else has got this problem: 1. soldier x is promoted (acting, paid) a couple of months before his next increment (IBD) and becomes substantive on the IBD date. 2. his new rank is at the pay level he would have gone on to anyway had he not been promoted and had reached his IBD. 3. the net result = other than the initial couple of months soldier x has not gained a pay rise for promotion, for a year until his next IBD date. JPAC and MCM unable to decide what should happen and noone else seems to know the rules for this. Is it just tough luck or promotion on the cheap?
