is, yes, it is very luck-influenced
A big reason troops tend to be "superstitious" (think lucky charms from an MRE) is because knowing that "luck" determines if you live or die can be rather maddening
And its easier to say X causes it
But luck (game terms, RNG) IS a part of real-world combat
"You can do everything right, and still wind up dead"
This is why the basis of tactics is redundancy
EVERYTHING in the military is about redundancy
You dont room-clear by yourself because if you go down, you have no cover
You go in a "stack" because if you go down, your 2, 3, and 4 man are there to cover and eliminate the enemy
You train to disassemble your weapon under stressful conditions, because your weapon WILL stop working, and a simple "reload" wont fix it
Yes, as this game gets more realistic, prepare for more RNG
Develop your tactics, as in IRL, to cover for these possible outcomes
Avoid all-or-nothing plays, because you could squeeze the trigger and "click"
Always have not just a plan A, but plan B-Z
If you make a play, without any thought of "what if this doesnt work", and then you die because your plan didnt work
Thats not RNG's fault
Thats yours for not planning
