Better Angels starts up with the Walker invasion that took place during Season 2 of The Walking Dead. The tactics of Rick and Shane are notably similar when defending Carl from the Walkers.
Downfall has this tactic both played straight and inverted. The Exequia Troops of Unohana's army are mindless drones that employ this tactic occasionally as skirmishers. They are repeatedly shown to pose occasional difficulty to even Lieutenant-strength opponents due to their sheer tenacity. They make no sound—not even when they're hurt or killed—and will keep coming until they're dealt a fatal injury.
In Enemy Of My Enemy, the Brutes try a version of this, charging in a solid wave of fur and fury against a wall of Jackal-shield-wielding Elites, in a scene reminiscent of soccer hooligans rushing a fence. In this case, the fence pushes back and holds firm, while the Elites' human allies fire down on the Brutes. It's stated that the Brutes were so tightly packed, dozens were dead on their feet because there was no room to fall to the ground once they were killed.
