"worth every penny if you're the infantryman and the tank is heading toward you"

To bad it isn't cheaper we could give every infantryman two! In all seriousness though if you are an infantryman in a Malaria infested swamp anti-malarial drugs are worth every penny too but the production of those are subject to competition so luckily they only cost pennies a pill and every soldier can have as many as needed. The missile's value to a soldier is not a justification for it's cost and if anything the high cost of something like that is detrimental because if it really is that great it means that not everyone can have one.
