I think the original framing and context is that soldiers are offered the benefits that would be offered to all the workers under a socialist governance but instead are offered those "socialist" benefits in exchange for service to enforcing the will of capital.

That isn't wrong, it isn't "incorrect" to say that it is "socialism" even if it isn't scientifically accurate to the word or our niche/specific political definitions. This would matter more on say, my home-instance Lemmygrad then a left-unity board especially when a lot of newer folks are on here. Words can have multiple meanings and those inflections can shift based on the context they're being used. More importantly, I think people hand-wringing and griping about it have more of an issue with puritanism with a bit of a lack of comprehension of context speaking that it's quite easy to just click on a user's profile and take a bit of a deeper dive. In fairness, I've done it myself with being too hasty. Some things I learned while here, I suppose.

In another meme made by the same creator, it's clear what they meant. Not "socialism is when government does stuff" but clearly capitalists and the ones they choose from political will enjoy the benefits we all would under socialist economy. Pretty clear.
