The truth is that most mil specs pertaining to electricals have nothing to do with quality of the device. They are to make sure that when a shipboard glide slope is transmitting to a jet 30 miles out, that when someone turns on the deck elevator motor that the signal to noise ratio stays well above the noise. It’s for when the airforce drops a JDAM guided by a battery powered reciever on board, that a radio signal from the local Al-Jezeera network doesn’t stomp out the 3 watt signal from 12 miles away. I know a lot about shock and vibration too. The one ton and two ton impact tables, and the vibration tables. In all the cases the military issues a notice to bid. I would not suggest using a lot of commercial gear in a lot of critical applications in the military. My coffee pot example was an over-simplification. I have however seen a coffee pot go thru shielded room testing for use in CIA/NSA offices(which each room is actually a shielded room made to look like a regular office, tight to 100db)
Nothing is well tested until it’s give to a 20 year old Army PFC. I was once asked how we could keep the troops from breaking things and I said you could give them a block of Titanium and they’d bring it back broken.
For a lot of today’s-——, only been in school all my life and my mom never let me hang out at the dirty, old car repair place-—the military is their first experience with equipment.
Fix, build, repair is something you pay someone else to do. More and more now a days a non or first generation American.
