depends on the situation, but prolly the marine. Most security is only useful for telling you how to avoid the bad things like death. Once the crap hits the fan ur pretty much screwed no matter what you have for security, remember, the attacker (assuming he isnt an idiot) would have taken a look at your security and found a weekness, not to mention will prolly have somethign of the element of surprise because he picks the time and place. There is no such thing as absolute protection.
