MikesPea,
I've heard both too. I got verbal orders after 9th week, with the orders being cut 11th or 12th week. AMDO school only classes up 4 times a year, so they try to put people into OCS classes that will graduate, and then go to AMDO school within a 2 month period or so (I was comissioned Dec 13, went to school Jan 10(?), you can bank on your husband going to AMDO school in Whiting for 10 weeks in the middle of march) The course is only ten weeks long. What can happen, is that if an AMDO is slated to graduate and class up in January, but rolls a couple times, this can screw up the orders. For example, an AMDO in our class rolled, meaning that instead of going to AMDO school in January, he had to wait until March, which affected his choice of orders (but he still got his orders before OCS was over).
To put it frankly (and to stop this longwinded post), unless something strange happens, your husband should have orders at the end of OCS. All the people in my AMDO class had knew where they were going the first day of class.
