The South Alberta Light Horse (SALH) is a Canadian Army armoured reconnaissance regiment of the Canadian Army Reserve. It traces its complicated lineage to the Rocky Mountain Rangers, and claims its direct ancestry to the 15th Light Horse, along with various other Alberta based cavalry units. The "Light Horse" designation comes from its light cavalry and mounted infantry origins.

Armoured reconnaissance is the combination of terrestrial reconnaissance with armoured warfare by soldiers using tanks and wheeled or tracked armoured reconnaissance vehicles. While the mission of reconnaissance is to gather intelligence about the enemy with the use of reconnaissance vehicles, armoured reconnaissance adds the ability to fight for information, and to have an effect on and to shape the enemy through the performance of traditional armoured tasks.
