The Life Regiment Hussars (Swedish: Livregementets husarer; designated K 3) is one of Europe's most victorious regiments and one of Sweden's oldest military units. It is still active today. The regiment descends directly from units set up by King Gustav I of Sweden (Gustav Vasa) in 1536, when Sweden was the first country in the world to introduce a draft set up of voluntary riders north and south of Stockholm. The regiment was very active in 1600's and 1700's and helped win several key battles for Sweden on the European continent.
