I found reference to the military study you mentioned, on Harvard University's webpage [cited below] and do not see any mention of Cyclobenzaprine there.

Cyclobenzaprine doesn't appear to be listed among others on the following LA Times article either, where they depict various medications retaining their efficacy 28 to 40 years past their official expiration dates.

But they do list several pain relievers along with a sedative and muscle relaxant known as Quaaludes... Since Cyclobrenzaprine is also a muscle relaxant, I'm sure it's capable of holding its own through the test of time, albeit there are also several factors (such a how it was stored, extreme temperature exposure, etc) that could cause something to degrade much quicker.

Hope this helps!
