Sauerkraut missions are not actually about sauerkraut - it's just a fun name for a military operation. Imagine playing a game of make-believe with your friends, where you pretend to be soldiers and plan out a mission to capture a flag or rescue a hostage. That's kind of what a sauerkraut mission is, but it's not a game.
In the real world, sauerkraut missions are planned by military units to achieve specific goals. They might be sent on a sauerkraut mission to gather information, destroy a target, or protect an area. Just like in your make-believe game, they need a plan and specific tactics to achieve their objective.
The name "sauerkraut" mission isn't random - it's believed to have originated from soldiers during World War II who were served a lot of sauerkraut, a type of pickled cabbage, as part of their rations. They named their missions after the food they were eating.
So, in short, sauerkraut missions are military operations with specific goals, and just like a game of make-believe, they require a plan and strategy to be successful.
