Looks like it was legit, but is now removed - which is strange because as CritGal points out, the price points don’t make sense.

From Patreon:

We don’t allow Patreon to be used for funding weapons or military activity. It is a violation of our policies, and so we have removed the page. No contributors were charged after February 1, 2022, and any funds in the account from before February will be refunded to contributors.
