You hinted at this in your last sentence, so I assume you're aware, but I feel like spelling it out anyways:
There's many slices of ~10-20k people you can divide the US (military) in, many of them overlapping.
What is the chance that in some year at least one of the slices will say "Hey, we had excess suicides!" - much higher.

It's a multiple comparison problem that you don't know is a multiple comparison problem because you yourself didn't do the comparisons. You just got the result of them.
