BUT Exsoldier, if they are caught they do neither, accomplish their mission or end their life.....then what?
Do you know what pffffft means?
Hence the "scram" contingency plan. You will react like you are trained. If you train to have your security compromised, then you have an automatic series of actions to take. You don't think (too much) about what the authorities are doing, you concentrate on following the contingency plan.
pfffffft? The only sound I know like that has to do with a suppressor on the end of a firearm. I don't know if it applies in the context you mention.
You are forgetting one thing; most of these online guys are not operators. I'd not be surprised if they were reigned in. Maybe even for prayer or other support.
They didn't stop on their own. They wouldn't know how.
