Choose from an intense dynamic action such as blasting the door or kicking them in. In this case, however, you can face opponents from the outside but also the inside. In many situations, therefore, a quiet action is more appropriate, like a slow opening of the door using a handle, the use of silent variants of weapons, etc. Before entering the room, it is recommended to use a camera to check the number and location of suspects.
