Targeting a specific country with hreflang

Cant seem to find any information on this, so its probably not possible. Figured I should ask anyway, if someone is wondering on the same thing.
But could I say, target Germany (Google) with english content, by using de-en or de-US on my hreflang? (Im using a subdomain "en".)

If not, how would you target a specific country for your keywords - with English content?

Could you take a glance at the following URL? I feel it will be of use to you.
