With NYPD, all military folks can get credit for some of their time served, but you have to pay for it. There are rules as to what time of your service applies and what does not. But you get it on the back end. Meaning if you did 4 years in the military, you may be eligible for 3 years of "buy-back." That measn 3 yeasr of it are eligible and you go to Headquarters and do some paperwork. They then tell you what each year costs. I have no idea the actual cost. I have heard rumors from $3500 a year up to $8000 a year. You pay them the $ and get teh yeasr at the end. That means if you have 3 years on...you don't do it till you have 17 years, in this case.
-In God we trust. All others, put your hands on the car and don't move.
