Why did the shell miss where your reticle was pointing?

Celivalnya — Gunnery Range is a free shooting trainer for tank games. It runs in the browser, nothing to install. The shell flies from the server-side reticle, not from yours — see for yourself what a snap shot, an unfinished aim, lead and a blind shot really cost.

Celivalnya: a moving target, the lead circle, your reticle and the server reticle, and the breakdown of the last shot

Blue circle — where to aim with lead; pink dashes — the server reticle; at the top — the breakdown of the shot you just fired.

Five modes

Single target

Aim time, snap shots and dispersion on a stationary tank. Watch the server reticle lag behind a fast turn.

Pop-up targets

Tanks peek out from behind houses one at a time — you never know which one. Finish aiming while it is exposed.

Moving target

Heavy, medium and wheeled light tanks drive between houses. Lead that accounts for shell flight time and the server.

Angled peek

A tank peeks out at different angles. Penetration of the lower plate, turret cheeks and side is calculated from the armour angle.

Blind

The tank is no longer spotted: the reticle “falls through” behind it, the gun elevates and the shell goes high. Learn where to aim to hit.

Every shot explained

A picture and a verdict, as in the mod's report: snap shot, not aimed in, too little lead, overshoot, network or plain dispersion.

Measurements, not forum myths

The server receives your aim 10 times per second and lags 70–85 ms behind it — at almost any ping (measured over thousands of shots).
Snap shots are expensive: turning slower than 5°/s — 65 % hits, faster than 30°/s — 17 % (108 shots from one battle). Keep your turn below 12–13°/s.
Shell distribution inside the circle — from statistics of 125 million shots: half land within 0.37 of the radius from the centre, fewer and fewer towards the edge.
Everything simplified or not yet measured in the model is honestly marked in the game itself — see “Honest about the model”.

The mod: analysis of your real battles in development

The same breakdown as in Celivalnya — but for your real battles: why each shell went where it went, where you were showing your side when you got spotted. Then advice on what to practise, and a check in your next battles whether it got better.
