In the south, the 1st Division handled the defense, along with the 15th Brigade of Brigadier General Lon Non; it was the calmest part of the front at that time. In the region of Takhmau, Route 1 and the Bassac River, the 1st Division was subject to continued Khmer Rouge pressure. East of the capital were the Parachute Brigade and the troops of the Phnom Penh Military Region. The MNK naval base on the Chrouy Changvar peninsula () and the Khmer Air Force (KAF) base at Pochentong were defended by their own forces.
