you can't negate the value of the particles just by continually bringing up random scenarios where they don't help. It's just silly. It's like saying that tanks don't help armies that much because after all, you can't use them to clean the soldiers' clothes. Well yes, you've got me there, tanks don't clean soldiers' uniforms, therefore you've shown them to be useless in a war.
what is this random scenario crap you keep going on about have you never watched any of the Dominion War episodes? Becuase those random scenarios are what usually happens in the battles shown which means pretty much they aren't random scenarios.
And no the particles don't help with major injuries which was shown when the chick Picard was interested in was injured in a cave in and said to be dying, she needed federation medical tech to survive.
So no I don't think that the particles will help in a war, mostly becuase you have done nothing to refute my point except to show that you have no idea how war works in Star Trek.
And it is not saying that tanks don't help armies that much because after all, you can't use them to clean the soldiers' clothes.
It is say that magic rejuvenation radiation will help soldiers except against bullets, explosives, and ect. aka what they usually deal with in combat.
