When we say someone "wiped the map", it usually means they have completely destroyed or defeated their opponents. There are a number of synonyms that can be used to convey this same idea. For example, "annihilated", "obliterated", "decimated", and "eradicated" can all be used when describing a force that has completely vanquished the opposition. Other options include "crushed", "extinguished", "demolished", and "devastated." Each of these words carries a sense of overwhelming power and dominance, and can help convey the intensity of a victory that leaves nothing but rubble in its wake.
