If it helps I’m currently using Danger Close as a “tool kit” for Vietnam and French Indochina War (platoon size actions) adding event cards etc. It won’t be everyone’s cup of tea but might be worth a try?
Failing that I’ve also enjoyed games with Force in Force, FNG and Bodycount (an old 1980’s Tabletop Games set that still turns up on EBay every so often).
In the end, experiment and settle on what you think works and is fun.
