Warning over SAM site

[HK_Seven]

Attempted to find rules/more info about SAM Site and ammo for the SAM before posting and couldn't find any.
I logged in this evening with a pop-up warning saying I could not have ammo in my SAM Site.
Not the end of the world but I could not find any related rules or articles on being a rule or reason why?

Loaded and powered Sam turrets are typically used as a PVP item. They only target player vehicles.  
Having a Sam turret is fine, if merely decorative. 
Having one loaded requires that you make very very sure it cannot target anyone outside of your enclosure, including in the airspace above your base.

Type 'define turrets' in chat while on server to read the basic overview.

Fantastic. 

I was unaware it would target player vehicles on PvE server. 

All good. 

Thank you.

No worries. I am glad I was able to help. Have a great one!
