(under the canopy, umbrella flowers bloom.) (the fire unit implements fire coverage on the "enemy" target.) War Eagles roar and umbrella flowers are everywhere. In early July, a group parachute landing key control drill of a certain brigade of airborne troops started somewhere in Central China. In the early morning of a military airport, hundreds of parachutists quickly completed the preparation work of umbrella arrangement, weapon hanging, equipment inspection, etc. with the help of the weak morning light, and then boarded the plane orderly according to the battle formation through multiple inspection lines. Accompanied by a huge roar, several warplanes took off in turn and quickly burst into the scheduled airspace. After flying into the airspace of the drill, the side door of the cabin slowly opened, the yellow light began to flash, and the parachutist quickly got up to get ready for departure. "Jump! Jump!..." after receiving the departure signal, the parachutist quickly gave instructions, and the parachutist rushed out. In an instant, umbrella flowers bloom under the sky. Facing the complex weather conditions, the paratroopers calmly operated their parachutes and landed in the target area. "Release the parachute and assemble quickly..." after landing, the paratroopers quickly separated from the airborne area and occupied the favorable terrain. Immediately, the reconnaissance unit flew unmanned aerial vehicles to conduct reconnaissance on the "enemy" position, the firepower unit covered the "enemy" target with firepower, the chemical defense unit went out covertly to carry out fire spray attack on the "enemy" bunker, and the assault unit launched an attack in the form of small groups of multiple routes and alternate cover... All operational elements cooperated closely to break through the core points of the "enemy" at one stroke. During the drill, the brigade successively carried out airborne operations such as formation airdrop, low altitude parachute landing, personnel assembly, and key control in accordance with the requirements of "full process, full elements, and full staffing", and honed its combat skills in close contact with actual combat.
