Just in case you are actually serious... ¶
Before considering a military for your "Space Nation" (that's still funny no matter how many times I say it), you may want to read the UN Outer Space Treaty, paying special attention to ARTICLE IV.
"The establishment of military bases, installations and fortifications, the testing of any type of weapons and the conduct of military manoeuvres on celestial bodies shall be forbidden."
I underlined the important part for you. Not that you have any chance whatsoever of actually becoming any kind of nation or having any kind of military, but I thought it worth mentioning anyway.
Stay awesome. :-)
