I'd have to say that "The Limey" has some good tactical action in it. There have to be a million other movies that qualify.
"Quigley Down Under" floats my boat. I love when he gives a wounded man a revolver loaded with one round, and tells him to make the most of it. The guy can either shoot him in the back as he walks away, or he can take his own life rather than die of thirst under the desert sun. Okay, so this is not exactly
tactically safe on Quigley's part, but I'm allowing him to substitute style and balls for tactics in this case.
Also a good watch for "tactics" is "Remo Williams: The Adventure Begins". (The finest series of movies that never became a series. LOL!) This one'll show you how to evade bullets even as you creep closer to your attacker, and then pop his mag into the air, catch it, and de-cartridge it with your thumb. Oh, then you can poke him with your super-strong fingertips.
But come on, what movie can beat "RED DAWN" for tactics?!
They pop up from camouflaged foxholes and mow down Central Americans...
They use women as bait to ambush Ruskies...
