In the battle department's data, there are also coordinates files left behind by the first-generation personnel.
Especially for global routes like Oasis Avenue, the migration routes are all fixed. As early as several thousand years ago, the Holy See had measured and experimented land markers within a 50-kilometer range on both sides of the route.
Then it was transformed into a complete set of artillery coordinate parameters.
This way, as long as the scouts on the front line or the observation points on the battleships confirm the enemy's location, they can directly report the coordinate numbers.
Then, members of the battle department can make micro-adjustments to the angle of elevation and aiming direction of the artillery through calculations and adjustments, precisely locking onto targets several kilometers away for beyond-visual range fire coverage.
