The KPA had been pushed to its limits and many of the original units were at much reduced strength and effectiveness by the end of August. Logistical problems wracked the KPA, with shortages of food, weapons, equipment and replacement soldiers common. By late August, the UN command had more combat soldiers in Korea than the KPA, and the UN had near-total superiority over the air and sea. KPA tank losses had been in the hundreds, and it had fewer than 100 tanks by September 1, compared to the Americans' 600 tanks. By the end of August the KPA's only remaining advantage was their initiative, as the KPA troops retained a high morale and enough supplies to allow for a large-scale offensive.
