Team Damage to Vehicles?

have you always been able to do damage to your own teams vehicles? I can’t remember

the reason i ask (Warning, Rant!)
I was in Mantis and two people on my team (they sat and are spawn all game didn’t get many kills. Annoying are whole team) threw sticky grenades at it and started shooting it with a turret on a Warthog until it blew up.

I had only been in it for 10 seconds when they did it.

I guess they wanted to Mantis, so when it spawned again I got it it and they did the same thing.

I am normally good in a Mantis (getting around 10-15 kills each time) but I didn’t even last 30 seconds because they just blew it up instantly.

I couldn’t team kill them to get them away either.

Give 'em bad feedback, avoid them in future.

Griefers are annoying but don’t rise to them.
