In this case, what I propose here, is nothing more and nothing less, than to add the mechanics of breaking the doors with impulse, either using the impulse of the soldier that avalanches on the door, or a gesture with some combination of buttons on the keyboard. The gesture would be similar to the one used to break the windows, but in this case it would be a gesture of the assault squads, which could surprise an enemy and also make unnecessary the use of the button to open the door. Since in those moments where quick action and the surprise effect is more important, it would be an undeniably superior mechanic.
Without further reference, pass message to the superior command.
I need to add that an easy way to implement this mechanic would be that when you run to a door and press jump, it breaks it with a kick. It could be with or without impulse. It would replace the action of opening up to destroy themselves, and the activator would be to jump and run at the same time towards the door within a collision volume in the area. It requires adding an animation to raise the leg and throw the kick in the air and some sound of effort e Emantched by the soldier in addition to the one of destruction.
