Why is Spaceforce is a good idea? I didn't get the joke.

Well, it's a good idea because it's very clear that the Air Force doesn't fully understand how to fight in low-Earth orbit and doesn't fully realise the ramifications of ceding control over that battlefield to Russia and especially China. The Chinese have some very impressive satellite-killers that, in the event of a serious shooting war, could cripple America's satellite networks and thereby destroy America's vast technological resources in just a few minutes. That would render impotent the highly effective American doctrine of Deep Strike using stealth and other technologies.

The reason why nerds like me find it funny, though, is simply because it lends itself so well to endless Warhammer 40,000 memes.

The instathot has a certain thiccness to her

Yep. That's kind of how I like them.

I envy that you can choose to get whatever rifle you can get

In the USA, you can buy quite a lot of seriously cool shit either online or in any military surplus store. The Yankees really love them their AR-15 platform – which is NOT a fully-automatic "assault" rifle, it's merely a dinky little poodleshooter. But if you know where to look, you can find some seriously powerful long-range weaponry and high-powered stuff over there.

I don't know if you can buy a fully automatic in the U.S

You can, but the paperwork and background checks required to own a Class 3 firearm are extremely onerous. And even if you pass them, the types of fully auto firearms that you can own are so tightly regulated that one might as well not bother.

The instathot has a certain thiccness to her. Looks like something Alexander the Great would casually impregnate on a night after coming from war.

I envy that you can choose to get whatever rifle you can get. I did a mandatory military service in a European country and after getting out, the military mandated that I had to have a fully automatic 7.62 G3. A rifle that was made H&K almost 100 years ago if I'm correct. It is ugly and unreliable as a blue hair feminist. Water, oxygen and dust can jam or completely destroy this gun.

I don't know if you can buy a fully automatic in the U.S but what you can get on the market outside of Europe is far superior compared to the junk I got.
