The test firing took place on the base's shooting range.
It was quite spacious here, about a thousand meters in length, far exceeding the mortar's maximum range of 700 meters.
To better simulate real combat, the instructor had a trench dug 600 meters ahead.
Dominic ordered the officers to fire at this trench as their target.
Of course, no one would be in there to report the targets!
The artillery officers played their role at this moment; they knew they needed to stabilize the gun and keep it level, then calculate the firing data based on the initial velocity of the shells and the target's distance, and adjust the angle accordingly.
This saved the instructors a lot of effort; they just needed to occasionally remind them of new issues to be aware of.
