I’m also pretty big into extending my life...but there will be - in the event of an attempted gun grab and other tyrannical actions by our government - many uses of Molotov cocktails. They are just to simple to make and use, and I cannot think of a single individual who looks forward to being imolated...so it is a pretty effective means of psyching an opponent out.
Is it always the best weapon? No, of course not. But it definitely has its uses.
BTW, the MRAPs may be armored against bullets and even mines, etc. - but how well do they protect their crew from being cooked when a large portion of the vehicle’s exterior is burning?
