Silent and Deadly
that is the strategy if youre behind the enemy lines. dont think you can handle the enemy with confronts with them, but you must kill them silently without being killed

Survive
Surviving is the only way if you wish to live. you must be survive if you think that you're outnumbered or outgunned by the enemy

Eliminate
Eliminate the enemy if you have all weapons you need, and all weapons you need is deadly or eliminate your enemy once they are not ready. if you have a chance to kill.. dont waste more time to wait
