The Delta Operation is a popular design game at the moment, and the gold farming mode within the game is particularly praised by players. The game updates its seasons periodically, and changes to the dog tag missions in the 3*3 new season of Delta Operation are of great concern to everyone. Knowing which missions have been changed can help with preparation.

The first change to a dog tag mission is Erudite 1, where the task has been modified to require successfully extracting 6 collectibles of quality greater than purple from any confidential or top-secret operation. This mission largely depends on the player's luck, but overall, it isn't too difficult. Another requirement is to produce a Precision Armor Repair Kit, for which players can prepare materials in advance and then craft a level 5 armor repair directly.

The second changed mission is Take and Give. This mission requires the player to personally kill two people and also extract 6 dog tags. Teammates can enter and then immediately withdraw, making this mission more troublesome for many players as the main change is not about submission but extraction.

The third changed mission is Starry Sky, which has actually become simpler. Players only need to go near the administrative building to pick up items, then drop them off, which can be done quickly. The key point is to avoid combat.

Next is Resolving the Secret Bucksh, which is another simplified dog tag mission. We need to investigate three password-protected doors, all located in relatively safe areas, allowing us to complete this task in one go.

This time, there are quite a few changes to the dog tag missions. Some missions have become more challenging, while others seem more complex but are actually easier to complete. It's recommended to first tackle the easier dog tag missions, and then address the more difficult ones based on the situation.
