I don’t necessarily want to jettison this level of crunch, as I think it’s integral to the tone the system is designed around, but fuck me if it isn’t a lot to keep track of
Allow me to disagree with the highlighted statement. A mistake old school game designers used to make is to try and reflect every fluff detail in the rules. You don’t have to differentiate an assault rifle in full auto from an SMG and in most cases, even an HMG. If you go down this route, you will need to account environmental factors, fatigue, time of day… which are also big influencers. But we don’t, because that’s what randomizers are for. Just bundle the difference in the randomizers.
You’ll say, correctly, “getting hit by a .50 cal is a world of difference compared to a 9mm”. That’s true. That’s fiction and setting, though. It doesn’t have to be reflected in the rules of simulating shooting the things in a game.
My advice would be to do exactly what you proposed not to: chuck the entire system. Use a generic system instead. Whatever you’re most familiar with: Cortex, Savage Worlds, Fate, GURPS…
What is your story about? If it is about handling the gear, then perhaps (perhaps!) keep the OG system. If it’s about anything else - a shared overarching plot you’ll write with the players; about how the characters react and evolve to their surroundings; about interpersonal drama; base building, you name it - use a different system.
Of the ones I listed, Savage Worlds is easily reskinned, Fate is easily tweaked, Cortex is a toolbox to get your game moving fast just the way you want it to feel, and GURPS probably already has a module for you to use. If you want to bounce ideas with other people adapting to Fate and Cortex, they both have very active Discord communities (I know, information silo, but that’s where the authors hang out). Good luck!
P.S.: I just remembered Cepheus (a Traveller retrocolone) has the acclaimed Modern War from Zozer Games. I have played their Hostile (Alien universe RPG) and the ruleset is essentially the same. There is some crunch, but easier than D20: https://www.zozergames.com/modern-war.html
It looks like it and Delta Green lead sales on military RPGs: https://www.drivethrurpg.com/en/browse?genre=320-military













The point is not that crunchy simulation is undesirable, but that every simulation model is an exercise in where to draw the line in what accuracy you’re losing to keep your goals achievable. OP has expressed the crunch is too much for them. “It’s okay to draw the line further away from accuracy” was the core message I was trying to convey.
