Sure, a deterministic engine can tell you what happens if every unit follows a strict rule set, but real combat is a mess of human errors, morale dips, and sudden flanking—things that never fit into a clean if-then structure. If you want to feel the chaos, throw some bounded randomness in, maybe a Bayesian shock factor, and then debug the chaos like a rogue bug. Otherwise you'll just get a glorified chess game that looks nice on paper but feels off in practice.
