Set controls around the engagement
Your controls should let you find a target, put the gun on it and withdraw without searching the keyboard. Build a consistent core layout, then add the functions your current lineup actually uses. A copied keybind file is only useful after you understand what each binding changes.
Keep observation separate from exposure
Put binoculars, free look and the gun sight within easy reach. Scan from behind terrain, then check whether the barrel has a clear path before firing. Seeing over a wall with the camera does not mean the gun can clear it.
Use lower magnification to search and higher magnification to place the shot when your optics allow it. Remaining zoomed into one target hides movement at the edge of the lane. You should be able to return to a wider view without moving the tank out of cover.
Make ranging and sight adjustment one workflow
Bind Rangefinder and Sight distance control so you can use them without taking your hand away from movement. Understand whether you are using the crew's estimate, an optical rangefinder or a laser-equipped system; they do not provide identical speed or accuracy.
Check the sight after ranging. The reading and the gun's current range setting are not something to assume from memory across every vehicle. Practice restoring a close-range setting after a long shot. Otherwise the next tank appearing around a nearby corner can be met with a gun still elevated for the previous engagement.
Separate shell selection from firing
Give ammunition types predictable controls and check the chambered round before exposing the tank. Selecting another type normally determines a subsequent load; it does not instantly exchange the shell already in the breech. Plan changes under cover rather than wasting a useful loaded round into the ground while an enemy watches.
Keep machine-gun fire separate enough to avoid accidental tracers while observing. On vehicles with additional guns or selectable weapon controls, test which weapon and sight each command operates. Do not transplant an aircraft weapon-selector setup into a ground vehicle and assume it performs the same job.
Separate emergency actions
Repair, extinguishers and smoke need distinct, reachable bindings. Test for conflicts with ammunition selection and movement. A key combination that works while stationary can fail when you need to reverse and look sideways at the same time.
Know which smoke system you activated. ESS can conceal you visually while leaving you visible through thermal sights. It is not interchangeable with smoke grenades. Whatever system you use, move away from the last known aiming point if a covered route exists; a screen does not stop a round already traveling toward you.
Add modern sights without losing the gun
Where fitted, practice thermal switching, the commander sight and the return to the gunner's view. Confirm which crew position has the equipment rather than assuming one thermal sight means every station has it. A bright shape still needs identification and a clear shot path.
For a vehicle with scouting, make the scouting command easy to use while observing. For missile carriers, rehearse the actual guidance and launcher limits of that vehicle. These functions belong in the same observation-and-withdrawal workflow as the main gun, not on keys you can only find while parked.
Give SPAA its own rehearsal
Where equipped, bind radar search, tracking and mode changes and learn what each display is telling you. A radar return is not proof that the selected weapon can reach the target or that the line of fire is unobstructed. Practice acquisition, engagement and disengagement rather than simply obtaining a lock.
Save an exported control profile after checking the lineup. Re-test an unfamiliar vehicle before the next match: range a target, fire the intended weapon, change view, deploy the intended smoke system and reverse into cover. Fix the binding that breaks that sequence, rather than adding more keys around it.
