Yeah, that's it, doesn't look like it has changed much over the years. I remember a kid showing up with his father's leather biker vest that hung down almost to his knees, my beebees bounced off of him. Next time I came with a 3 foot x 2 foot sheet of 1/4 inch plywood with an improvised handle on the back, we were like a couple of ironclads going at it, we later on graduated to paintball guns playing capture the flag.
Nowadays there is quite a lot of "airsoft" activity - much lower muzzle velocity and plastic BBs. More realistic than paintball, though the activity centres tend to run both I think. I don't do in for this mock-battle stuff but I see in the dealer's that the gear looks very "military" - I can see why people come to the attention of "armed response" if they brandish them in public. I couldn't tell if the pistols were real without picking one up.
