I expect an airsoft venue is actually a private space, not a public one. Airsoft but-actually-in-public would have people concerned about a terrorist attack, not being recorded for insta.
To that extent, the hobbyists who like to create content for the internet should be asking for consent since their footage, and arguably their clout, depends on the participation of everybody else in the group. Otherwise they're just traipsing around a private plot of land all kitted up but with nobody to shoot. If they're monetising that content then they are profiting from the OP's likeness.
This is not far removed from the (fully understandable) blowback on influencers recording themselves (and often other people for rage-induced clout) inside gyms. These are also not public places.
