The last time a question like this was asked, I said it was when I enlisted in the US Army on Sept 5th, 2001 instead of Sept 12th, 2001. But in reality I probably would've enlisted either way (I was drinking the kool-aid back then) and when I enlisted it was on something called the Delayed Entry Program; I still had to finish my senior year of high school and didn't leave for Basic Training until June 2002.

The actual life-changing moment that came out of that was taking advantage of the Hometown Recruiting Assistance Program right after I completed AIT. It's essentially a 2 week temporary duty to go back home wearing your fancy new uniform to convince all your old high school buddies to sign up and be cool like you. I took it, did a couple recruitment events, signed up no one, and just enjoyed some free vacation time. This was March 2003, just a couple days before we invaded Iraq.

When I graduated AIT (your actual job training after basic training) I got orders to report to Ft Hood. Another guy, Watt, got the same orders. We had gone through Basic and AIT together, had the exact same MOS. I took HRAP, he did not. At the time, there were 2 major units on Ft Hood: the 4th Infantry Division and the 1st Cavalry Division. Watt showed up at Ft Hood and was assigned to 4th ID. I showed up a couple weeks later and was told that 4th ID was all filled up, so I went to 1st Cav instead.

4th ID deployed to Iraq in 2003, 1st Cav didn't deploy until 2004. Because units were basically on a "1 year deployed, 1 year back home, 1 year deployed, 1 year back home..." rhythm this meant I ended up getting stop-lossed instead of getting out of the Army in 2006 when my original 4 year enlistment was up. While I was extended, I was selected to receive retraining on newer, modern equipment instead of the old crap designed to fight the Soviets I was originally trained on. This new training, and some contacts I made while on my second deployment, led to me getting a job with a defense contractor doing the exact same thing after I eventually got out. That job was overseas, where I happened to meet my future wife. And even though I'm in a slightly different field of work now, I can still draw a straight line between getting that experience and contacts and how I ended up where I am now.

The alternative, if I hadn't taken 2 weeks vacation in 2003, is that I most likely would have gotten out of the Army as scheduled in 2006 but without any training that was directly applicable to a civilian job and without the networking contacts to land an overseas contractor gig.
