The fact is that a military force is used, not just to parade around a parade ground with boots and buttons shined to a blinding sheen. People join the military for many reasons, it is true.
But, if the military does not have a very good chance at actually doing any fighting, then it de-motivates the people who actually are good at that sort of thing from getting involved, and de-motivates anyone providing any funding from actually using new and updated equipment.
To imply that those who actually are suited to direct combat roles are somehow inferior to your evidently genetically, morally, mentally superior self is not having an accurate view of the world.
It's like saying that a doctor that enjoys surgery is twisted because no one in his right MIND would enjoy cutting people open and removing parts that are diseased or defective. How could anyone be so sick as to enjoy cutting people open? Oh My God what a nut case!
So, to reiterate my point, if we don't need the stuff we have, what motivation is there to buy newer, more modern stuff that we don't need?
This is the mentality that has to be overcome if there is no active participation in utilization of the equipment in all aspects of its designed capabilities.
