Which of the following is NOT a method of destroying pack animals?

The correct answer is that "pacify" is not a method of destroying pack animals. This term generally refers to calming or soothing an animal rather than inflicting harm. In the context of mountain warfare and the use of pack animals, destruction implies options that would incapacitate or kill the animal, which is not applicable to the idea of taming or calming it down.

The other methods listed—strike, cut, and shoot—are all aggressive actions that could effectively lead to the destruction of pack animals. Striking can include physical blows or impacts that cause injury, cutting encompasses the use of sharp objects to inflict wounds, and shooting involves using firearms to kill or severely injure the animals. These options are aligned with destructive actions, contrasting with the non-destructive intent represented by 'pacify'.
