>>523009>How is it not?
Where as any serious simulator is doing a fairly accurate job of simulating the subject it depicts, be it aircraft or driving etc.
Arma simulates the mechanics of a human body holding a gun extremely crudely and where as you can control and drive quite accurately with a joystick or a wheel.
A mouse + keyboard are a shit analogy for the bio-mechanics involved in pointing and firing a gun, and moving around on a pair of legs IRL.
Soldiering is just as much about physical stamina and dealing with the severe psychological stress of endangering your life when exposing yourself to fire.
Neither is present in a computer game. All that is left that is vaguely analogous to real combat is the maneuvering for effective positioning.
Much of which becomes invalidated by the super human fitness of the avatar traversing the gameworld.
While a realistic flight simulator game may be up to 90% real in how it translates to the actual experience (subtracting the psychological stress and forces involved)
Arma by comparison is more like 10% real in how it translates to the actual mechanics and challenges of what it attempts to depict.
Calling it a simulator is more indicative of it's ambition than what a videogame can actually deliver upon as of 2016.
