Kind of like the Covid virus. We're just going to have to learn to live with casualties.
My point being that anything that isn't inherently mobile is too vulnerable to enemy sensors (CB radar, OPIR, EW assets to name a few) and counter-battery fire, and thus is of limited utility against a peer enemy that can truly dictate the tempo of operations.
Nothing is ever 100% but no excuse to make things easy for the bad guys. I'm assuming you didn't actually mean "fixed" and that it was just a poor choice of wording.
