It depends on the camp. Usually rangers may not be able to eject a group no matter how obnoxious they. This is because the offending camp can always say that none of them are sober enough to drive, so their stuff isn't going anywhere... and after the ranger leaves, the result is the person whom they thought turned them in gets their stuff vandalized.
Thankfully in SPs here and a lot of CGs, the ranger then calls the local sheriff, who brings the paddy wagon, arrests the whole group, then has the local tow company with the super-sized truck come in to finish the job.
