This article examines the geographical reach of IHL during an armed conflict between a State and a non-State organized armed group. Its purpose is to explore how location affects the applicability of the differing legal regimes. Discussion will focus predominantly on noninternational armed conflict (NIAC), for that genre of hostilities poses the greatest interpretive conundrums. It is an inquiry of momentous practical importance since IHL's range (or lack thereof) influences operational planning and mission execution, determines how civilians and civilian objects must be protected during hostilities, sets the applicable detention regime, and affords avenues for enforcement of norms that are not otherwise available.
