for those relatively senior guys who think the STD won't bite them,
while I don't have any numbers to back me up, I'd bet that the majority of guard/reserver participation is in the more junior folks.....and, how will the company accomodate mil leave requests for those folks.

some units ask for 8+ days a month already......wouldn't be too hard to make the mil participation incompatible with the STD.....also don't think too many commanders willing to lose their troops for 3 bid months.
