Well the OP car is a 74k MSRP'ed car. Judging from quality_sound's signature, the MSRP is most likely at least $5k lower (6MT and no EPS). That will explain the lower payment.
The military price is still higher than ED price, so if you want to save the most you can always go the ED route.
As I mentioned before, you can get the 74k MSRP car for ~$67k with the spring credit, if you are in a competitive market.
