The US army spreads militarism by promoting sales of army-branded guns, clothing, and video games.

I don't think we should ban, or censor, video games. There is no reason to believe that they make people violent. It is not clear that they made Nik Cruz violent. But even if they did occasionally do that, censorship is a threat to human rights.

Most video games are unjust because they are nonfree software. That is a good reason to refuse to have them on your computer. But that is a separate issue.

However, it is clear that selling US Army fan material of any kind promotes militarism, and that increases the danger of violence that can kill thousands or even hundreds of thousands of people — in other words, the danger of war.
