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. :-)

Who says we must abide with the rulings of the UN?

Well, considering that Asgardia has stated the intent to join the UN, I would say the leadership does.

> on celestial bodies

Just build the free fleet in space. It's even better, because can be moved and concentrate forces by need.

the rules are not for a space nation ...only for grounders

"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.” 

I especially liked this part, one question though 890679, if that is your opinion, what are you doing here?
