Wow! Some people are incredibly slow on the uptake.

Every poll of "career" soldiers that have gotten out in the last few years have cited "increased operations tempo" (deployments) as the reason people who should have stayed to retirement, but didn't, got out of the Army.

There are around 135,000 troops in Iraq. Another 17,000, or so in Afghanistan. 37,000 in Korea. All of these troops rotate out after 12 months and are replaced. For a total of 189,000 a year on deployment, in just those three areas. (Let's not forget the troops we have deployed in Bosnia, Kosovo, and the Sinai, among other places) The Army has a standing strength of approximately 495,000.

Do the math. It's not that hard to figure out.
