You can go drive past them, even stop to use the porta-potty. (ok, maybe not recommended) I've antelope hunted over there a lot. (East of Harlowtown) and it is as empty as it gets in the contiguous US.
They could probably shoot it down without making much debris. And even if it made debris, at most it would hit a cow. The reality is it's not collecting anything of value.
Are the silos even a secret anymore? With ubiquitous satellite coverage, I assume that anything even possibly a launch site is extensively monitored. To say nothing of traditional mechanisms of gathering intelligence.
