| "A lot of tactical planning is required to successfully conduct close-ranged offensive and defensive warfare within complex terrain. Hand-to-hand combat in narrow corridors and collapsed passages is quite the test of a force's training and organization level." <Sandstorm> Allied units caught inside the sandstorm will have reduced ATK, continuously take damage over time, and have extended redeployment time; Enemy units will instead be slowed. | |
