Sniper Training is an achievement that requires the player to kill one guard on each tower of the Ranging Guild using a regular shieldbow.
All 4 archers must be defeated in one go (e.g. must kill each archer before going down the ladder). Bring food to heal, or a prayer potion to restore prayer points if using Protect from Missiles. The final blow to each archer must be done with a regular shieldbow, an oak shieldbow and above will not count. Alternatively players can kill them with whatever Ranged weapon they want if they switch to shieldbow while the finishing blow is travelling to their target.
