I cannot laugh when a stupid teammate shoots my vet3 Tiger Ace in the back, damaging its engine and leading to its destruction.
And what kind of drugs are you on that you think firing at your own tanks on purpose is realistic?
Must be some pretty funky stuff if you also start to laugh when a teammate is killing your armor.
Its not that a 50-ton tank is somthing so small and agile that dont realize that it is coming into your line of fire.
