Since Operation Flashpoint doors have always opened the same, why is their no animations of the player actually opening the door?

In my eyes their should be different animation types for opening the door,

silently: where the soldier actually grips the door handle and the door is slowly opened.

Normally: where the door opens normally but obviously with the handle grip animation.

Forcefully: this could either be kicking through the door to the door actually falling over because of force.
