thats wikipedia and the forums, neither of those are valid sources, and that wikipedia excerpt doesnt even support your argument, it says the vehicle could fire at long ranges and then move after.
Oh, really, what is its validity, then? Signing up for a secret program to find out? No common sense in this community whatsoever. Screw this.
you need one primary source, or multiple secondary sources same as always (wikipedia is a tertiary source on a good day, and the forums is nothing)
this is very common, and incredibly reasonable, gaijin cant just trust whatever anyones says, and if they cant find information its better they come up with something rather than just trust some random on the internet
nobody is asking you to share classified document, in fact rather the opposite, nobody at gaijin wants you to give them classified documents as it carries immense risk for them and you
