Joint Firing Drill pays Drill Coins for a rotating combat challenge. Its objective changes, so a successful farm starts with reading the current rules.

Farming tips
A fast-clear score favors a team that handles the stated objective efficiently; raw damage is not always enough.
The format rotates, so rebuild around the current conditions each time the drill changes.
Repeat, collect and use
Repeat during an active drill up to the available ticket limit. This is a scheduled mode with limited entries, not a permanent unlimited coin farm. Stop after using the entries you want or when the shop target is funded.
Common mistakes
Using a raid team without reading the drill rule: the special objective may require different roles or tactics.
Ignoring armor matchup: check the enemy type before selecting attackers.
Leaving coins unspent: visit the matching shop and exchange them for a planned reward.
When to stop or switch
Stop when you have earned enough coins for the intended shop purchase or when your available entries are used.
