Training is punishing to ensure that the Sri Lankan Army Special Forces Regiment remains a high quality revolutionary outfit in the country . The Selection test consists of several stages such as Weapons handling , underwater training , Close - Combat training , Live Ammunition training , Jungle warfare , survival , Reconnaissance , Sniper training etc . After undergoing basic military training , recruits are deployed into several treacherous terrains such as jungles without any equipment or weapons and are ordered to survive for a period as specified by the relevant instructors ( Usually 45 – 60 days ) . The recruits who succeed this initial selection test are given several more selection tests based on physical fitness such as Sprinting 50 miles ( 80 Kilometers ) within 12 hours without equipment , sprinting 5 miles ( 8 kilometers ) within 40 minutes with equipment , mountain climbing , underwater diving etc . The Recruits who pass these physical fitness selection tests are selected for special warfare training . The Recruits who qualify the special warfare training are given furthermore specialized training according to the special operative type they prefer . However when selecting operatives for the LRRP ( Long Range Reconnaissance Patrols ) only the current ( Active ) servicemen of the Sri Lanka Army are admitted for selection with a service record and a medical report suiting the specifications of that of the LRRP selection course .
