Artillery is pre-planned or requested with turn delays, approval rolls and range/deflection error.
How it works
Soviet fires follow a fixed pre-game schedule that can only be lifted or shifted; US fires use a target list, requested one turn and arriving call turn +2 (reference points) or +3 (targets of opportunity), with supporting fires needing approval rolls (e.g. 155mm 4+, 4.2in mortar 5+). Range and deflection errors are diced in 50 m/25 m steps except for once-per-game final protective fires. A template ellipse covers targets; one die per vehicle gives suppression or kill by target type (kill of tanks on 6).
Fire on known reference points (listed target numbers) and receive it the second turn following the request, or, 2) Fire on a target of opportunity by adjusting from a known reference point and receive it on the third turn following the request.
