The operator's workflow
From orders to impact
Read the order — pull the mission details from the teleprinter and note the target, bearing, distance, and constraints.
Measure and solve — plot the target on the tactical map, enter the range into the ballistic calculator, then choose shell, charge, elevation, and rotation.
Load and fire — work the mechanisms by hand, arm the correct gun, take the shot, then verify the result through reports and reconnaissance.
