Boomer's battalion, hidden in reserve and training for the next offensive while the raid unfolds.
The 106th Bloody Leeches were deliberately left out of the opening moves of Operation: Snake Pit. Under Boomer they stayed hidden in reserve, training for the next offensive, positioned so that any naga force exploiting the understaffed southern border while Tran moved west would run face-first into them.
The contingency became less pressing once Carl learned that Prepotente had already gutted the naga army, but the battalion remained the insurance policy behind the whole southern flank.
