I have been a security guard in regards to physical and asset security to include bar bouncer/ID checking, guarding buildings and assets, sporting events and concerts, hazardous termination (securing premises and protecting employees of a company that released one of their own from the company, with regards to fired/let go employee having hostile behavior due to newly released status), protective security support for sports teams or local/state government officials. I have also done security in the cannabis industry to include guarding of dispensaries, grow houses, labs, and events, as well as money transport.
I also have a military background in the US Army, been in 10 years so far, and I have contracted overseas.
I agree with @Gladlin , we do not have any orbital platforms or off-world bases yet, but as a newly-formed nation, we still require a standing military to protect Asgardia. Given that we do not have physical borders, I guess our jurisdiction extends all across the globe, and we aren't bound by any one nation's laws, so my guess would be international litigation? But on a national and state level, we do have to abide by the laws of our resident country---so far ;)
But yes, as a nation, we *do* need a military/security/police force, because without one to enforce the laws of our nation and protect our citizens and government, there would be room for a foreign force to attack us.
