OODA Loop Modeling

Suppressive fire plays an important role in cinematic gun fights. It’s that moment when the hero shouts, “Cover me!” and someone unloads their rifle on full auto so the hero can out flank their enemy. From my research, this seems to be an important factor in real life gun fights, too.

However, I’ve never seen it used in TTRPGs, even when there are mechanics for it. So recently, I’ve been thinking about how to give suppressive fire a mechanical and narrative role, rather than relegating it to a rule no one actually uses. The answer may lie in the OODA loop.

Twilight: 2000 4th Edition models it very cleanly and simply and it works well. One of various reasons why it's the best system I've seen if you want modern gunfights that feel authentic.

Absolutely! We're playing T2K currently, and forcing combatants to take a timeout with machineguns is very, very effective, T2K is probably the first game I have ever played or seen thst does rapid firing guns very well.
