Well, I’m going to attempt to answer this question in hopes that if I am talking out my rear someone will rip me a new one. I will use the term O-3 (Capt or LT). Making O-3, and augmentation aren’t necessarily related. You have a reserve commission, and are serving active duty until a democrat president is elected at which point the military will downsize, and the only men and women left standing will be the ones that were augmented. Everyone else; well, the military doesn’t need you any more until we re-elect a republican and go back to war, otherwise try and attach with a reserve unit somewhere so you can play military on the weekend.
Augmentation usually happens at the same time that you make O-3, but I suppose it could happen at another chronological time???
To give you a case study, that I know was somewhat common not to long ago, I will mention my TBS company commander, a major. He was an infantry guy enlisted, then officer – when augmentation time came around he did not augment as an infantry officer, but a communications officer??? Why is this? I assume it is all of the career balancing above my pay grade. This is what the Marines do, and I can only assume that the Navy does the same, since this order shoots down from congress.
My understanding is that it is a way to get rid of you if you suck.
The way I look at augmentation is that it is a job security plan for whenever the democrats make their comeback. It lets you become part of the good ol boy club.
That was all beatin around the bush, to make the final plunge – no, it will not affect your time in service. I assume that you are thinking in terms of retirement, and all of that info would most likely be in the uniformed services almanac. When you are active duty, you are active duty regardless of the R, it only makes a difference if you are in a reserve unit, and I don’t know much about that.
Hope this helps, and I was talking out an orifice other than my mouth for half of this, so please correct me if I am wrong.
Cheers,
Andy
