If you have watched videos of other players playing World of Tanks you’ll see that some of them do little movements that seem to be pointless. Whether it is forward/backwards or left/right some players move around and don’t completely stop until they need to shoot or aim at a weak spot. I refer to this as “wiggling” even though there isn’t a coined term for this tactic I find it describes it fairly accurately.
Wiggling does a few things. Firstly, it throws off some players since they are fixated on shooting a specific shot, and moving that spot slightly left/right etc. will make them aim for a second or more longer(and thus improving your survive-ability). Secondly, once you master wiggling you can time reloads and at the last second you can shift your tank to make their shot hit a sharper angle, strong point, or your track. , And lastly even if you can’t time shots or are against a decent player it still adds a bit of “luck” into whether they damage you since it might hit at a sharper angle, near a track, etc. etc.
Oh and I almost forgot! Remember your friend artillery? It is much harder to hit a target that isn’t sitting still or traveling in a straight line with spotted than a tank moving all over the place! All it takes is that slight movement to go from a shell landing directly on your tank to that shell landing just off the side.
Keep in mind that you don’t want to be doing three-sixties out there! For example a tank like the T110E5/IS-7 you’ll want to stick with moving forward/backwards or just slightly tapping left/right since your armor is most effective pointing straight ahead. Other tanks that are lightly armored such as the M46 Patton /Tiger a lot of the time you know your armor doesn’t stand a chance, so wiggling a bit more to hopefully get them to hit at a bounce angle or 0 damage a track is more suitable.
