Yes, but not exactly. They indeed make tougher equipment. But since they
have to cover a wider range of external variations, they have much less
options to make the equipment tough. In the extreme case they may have to
compromize lifespan in one condition to still make things work in another
Since we may have a much smaller range of variations, we may increase
lifespan a lot over several military equipment.

Hmmm, can you give me an example of a thing where we don't understand why it
failed? (Just trying to understand what you are talking about.)
