Exalted. In second edition, the Sidereal Martial Art Obsidian Shards of Infinity Style actually has a charm that allows you to choose a bittersweet ending, forcing fate (i. e. the storyteller) to resolve the conflict in one of several different ways.
The Battle for Macragge(Warhammer 40k): Hive Fleet Behemoth was stopped...After it consumed hundreds of world, killed billions of people, and completely wiped out Ultramarines 1st company(1/10 of their fighting force). And it was only a scouting party.
That's just in the numeric sense. First Companies tend to hold the veterans and elites of the Chapter. An entire Company, the Tenth, is also composed of pre-Space Marine stage Scouts.
Behemoth wasn't really a scouting party, just the first of many.
