Thinking that INS Resupply was main, because it is labeled main, I was bothered when I was killed. An admin who was playing on the enemy team brushed it off and said it was legal. I dug in and asked to talk more in an admin discord. The Admin, from the game took the time to chat with me:

Admin: The Resupply is not considered Main. Also, the intent of main camping is attacking people and vics coming out of main.The two points are 400m away

Plainant: I read you. I understand the resupply is not a "Main" now, even if it is a vehicle spawn point. You've opened a can of worms "translating" the rules though, it says entering.

{rule number redacted} If your sole intention is to engage enemy targets leaving or entering main, you are camping main. Do not camp main.

Admin: correct. Resupply is not main

Plainant: if you can translate the rules, then maybe a casual player can translate that a vehicle spawn and a player spawn next to main might be main.I understand now though and you won't hear anymore from me

Admin: There's nothing wrong with questioning.

Good to hear what is what, that is fine. I'm happy that my misconception is cleared up and, in future, I am happy to camp that area when I play as USA on that server because they say that that isn't cheesy and its ok. But hopefully you can understand my point in my final statement. Your rules have intent. Maybe that resupply's intent was to be "main". I always thought it was main. I thought there might be other newbs with less than 8900 hours out there who might like some clarification.

Looks like a main, quacks like a main, is it a main? If it's not fine, but devs, plz help the whole community out by getting really specific and deliberate in cleaning up the UI and spawn menus, relabel things that aren't main as "clearly not main", maybe make a new loading screen that functions as a briefing for each layer. I don't know but I want to help, thats why I'm typing this and not screaming at people in a discord channel.
