Do you have any context as a reference or were these direct translations from another language? I ask because I have never heard of "stand off" being used in front of either of these words before. "stand off" is most commonly used to refer to there being a delay in action from everyone, just before a situation of conflict.

Hi my friend The best translation must be in the sentence or phrase but I think standoff delay or weapon means resist or endurance for those situation

thank u

Stand off means getting away. Do you have the context?
