Brosnatz. An affectionate term for my Army contacts that on a regular basis have my back in civilian life also play call of task together. Is a play on terms obtained from Russian specialized Forces "Spetznatz". While brosnatz usually are male, women may also be a brosnat when performing anything far above the call of duty as a pal. Anyone can be a brosnat but my Army contacts tend to be my most useful brosnatz.
