1. an aiming phase
That includes
wind up,fire aim
2. (the shot itself, as far as I know it does not take time?)
That includes
burst duration
3. post-firing-time
That includes
wind down, cooldown, fire aim, ready aim, reload duration
Then it goes back to #1 until the magazine is empty (also here: where do I find the magazine size-stat?).
It is "reload frequency" which tells you the number of burst it will fire before reloading.
If the weapon fire single shot it burst is one.
If it fire automatic it is burst duration*rate of fire.
Which also means a Churchill should go down to Pioneer MP40s at some point.
No low chances bellow 3% are not calculated small arm firing vs armor +30 cannot penetrate.
Range effects:
