Can you take your dollars in to the government and redeem it for units of "military might", whatever that means? You have it backwards. The military is an instrument in protecting the US dollar's dominance, control and influence as a reserve currency.
No, but you can pay your taxes with USD, and stay out of prison, which is kind of nice.
So I don't think that it's a good argument for the USD being backed by value.
