I recommend " Anti-chemical Defense Vanguard ". Although it's not the end, it has elements such as the female protagonist's rebirth, the army, and the special forces. In addition, I recommend some other novels that are similar to military transmigration, such as " I let you manage the rookie team, but you actually became a special force?" " The Extraordinary Years of the Special Forces " and " I've Been Checking In Since I Was a Special Forces Soldier ". I hope you like my recommendation.
