In a zombie outbreak, there may be many times when one (hopefully with a small contingent of armed survivors) will have to inspect a building or structure where there may be zombies lurking. Possible reasons include (but are not limited to) establishing a new shelter, scavenging for supplies, rescuing a trapped person, or simply retaking the area, one house at a time. Fighting zombies indoors puts survivors at a disadvantage. The advantage of killing at range may be greatly diminished. It can be difficult to wield melee weapons in unfamiliar or confined quarters, and the risk of wounding fellow survivors is greatly increased. Disciplne, attentiveness and solid leadership are crucial.
