You should read some memoires from higher-ups in the military instead of trying to lecture people about something you have no experience with. Military leaders will say they don't need more equipment, but politicians will spend a ton on it anyway because the equipment is built in their district. Military advice is often ignored by politicians in order to score political points, like when Obama ignored advice to increase military presence in Afghanistan to regain control, and instead let it drag on with insufficient resources, ensuring it was a waste of time and life.
