Dismounting

Dismounting is the act of leaving a mounted position or detaching something that is mounted. The term is used in several contexts, including riding a horse or bicycle, departing from a vehicle such as a train or aircraft, and detaching a storage device or filesystem in computing. The opposite action is mounting, which involves placing or attaching something in a ready or active state.

In horseback riding, dismounting describes the process of getting off the horse and returning to the ground. It is typically performed after a ride or lesson and may be assisted by a mounting block to reduce strain on the rider and horse. Common elements include bringing the horse to a halt, maintaining hold of the reins, and swinging the leg over the saddle before stepping down and taking weight on the ground. Riders are advised to keep eyes up, wear a helmet, and ensure the horse is calm and standing square to minimize risk.

In transit or military contexts, dismounting refers to exiting a vehicle or aircraft. This requires awareness of surroundings and potential hazards, maintaining a low stance as appropriate, and clearing a path for teammates or passengers. Training emphasizes orderly, rapid exits with weapons and equipment secured unless needed, and ensuring the exit area is safe before continuing operations.

In computing, dismounting (also called unmounting) describes detaching a storage device or filesystem from its mount point in the directory tree. In Unix-like systems, the operation is performed with commands such as umount; in other environments, similar procedures exist under different names. A dismounted device should be safely removed only after the system confirms it is no longer in use, to avoid data loss or corruption.
