CONSECUTIVE NUMBER. -Do not confuse the consecutive number of a directive with the four or five digits that make up the SSIC. A consecutive number is added to an SSIC following a period (.) to indicate the consecutive number of directives issued by a given issuing authority that fall under the same SSIC. For example, the SSIC 5510 with a consecutive number of .1(5510.1) indicates this instruction is the first dispersed by the issuing command. Instructions numbered 5510.2 and 5510.3 would indicate they are the second and third instructions issued under the same SSIC. REVISION INDICATION. -When a directive has been revised, it is assigned an alphabetical suffix following the consecutive number; for exampIe, 5510.2C. In this case the C indicates the third revision to the directive; A would be the first revision, B the second, D the fourth, and so on. The letters I and O are not used as alphabetical suffixes. 8-5 4000 9000
