So one thing that has been quite a Grey area for me at least while learning how to play World of Warships, was the art of the aim. How to get that that "perfect" lead so that your shots always land on target (citadel). Obviously the more you practice the better your aim becomes, as you start to feel the target you become better able to anticipate where it will be in 5, 10 or 15 secs time; and so can adjust your aim accordingly!   But in the beginning its always nice to have a simple guide to help you get started, and I am sure most players eventually develop their own theory on how to aim so that they hit the target (citadel).   What I am going to share here is a very basic guide on the theory of aiming I developed during my many trials and tribulations of missing my shots and fine tuning my technique. I have come up with something that pretty much works on most ships when moving at average speeds for their class, with guaranteed hits on the citadel of your target.     CITADEL: The citadel is the most vulnerable part of the ship, of which landing shots here will incur maximum damage to the target. It is usually located beneath the smoke stacks in the middle of the ship:     The following guide is based on aiming at ships at a range of approx. 14 km away!      CROSSHAIR: First off what is the best crosshair to use for aiming, I find this one is best as it has clean lines and diagonals that help with aiming at ships that are moving in any direction:     AMMO SELECTION: The best ammo to use for penetrating armour are AP Shells (Armour Penetrating Shells), as these shells weigh more and are designed to penetrate the most heavily armoured parts of a ship, usually the citadel is protected by a thick layer of armour, that can only be penetrated at a close enough range to the ship and when it is broadside to you. AP Shells will ensure that penetration.     AIMING: Different ships move at different speeds, which means the lead time will vary depending on how fast the ship is moving. BBs (Battleships) are the slowest and thus have the shortest lead. You will notice along the left and right of the crosshair there are tick marks at intervals: 5, 10, 15 etc. It is these I use as the point of perception of where to lead my target when shooting. While aiming I will line up the tick mark axis with the waterline of the ship and place the relevant tick marker at the bottom of the ships bow. Now assuming the target ship is broadside to you and moving at full speed...     Battleships / BBs: I lead by Tick 5 for battleships     Cruisers / CAs: I lead by Tick 10 for cruisers     Destroyers / DDs: I lead by Tick 15 for destroyers         Disclaimer: This is by no means a full proof aiming guide for every battleship to hit every other ship, other factors can affect the lead time of your targets, these include the ballistics of main battery projectiles like speed, shell angles, shell weight, dispersion etc, even ship speeds can be very different. Shells from US Battleships are slower and heavier than shells from German or French Battleships, thus have steeper trajectories and take longer to reach their target than lighter shells.   Please take these things into account when aiming at a target, but you can use this a guide a basic reference to help you get started. As you practice your aim, it will get better and you will develop your own aiming style. I wish you all the best of luck in hitting those citadels, this guide will hopefully help you hit a few more!
