After completing the mission of penetrating the area in the previous episode, entering episode 14 of the program "Brave Soldiers", the soldiers - including singer MONO - entered a more intense phase when chasing a group of drug criminals with smuggled weapons from across the border to Long Luong commune, Son La. This time, the mission was deployed with a " stronger" plan, requiring soldiers to suppress but not cause casualties, requiring courage, alertness and the ability to coordinate absolutely accurately.
One of the most important tests is training on live ammunition with AK-47 guns, where every soldier must master the heart rate and keep a strong spirit every second. Youngest MONO impressed when shooting 4 consecutive shots - an excellent achievement for amateur players, showing concentration and a progressive spirit. Teammates could not hide their admiration for the young singer's serious attitude and efforts.

Episode 14 also recreates the legend of the battle of Dragon Hill - a resounding achievement of the Vietnam People's Public Security force in the fight against drugs. From the real story, the soldiers continue to walk in the deep forest, carrying more than 30 kg of armor on their shoulders, crossing dangerous slopes to recreate the battle.
When the armed criminal group arrived, the combat center communicated: The group of subjects had a very large number of weapons, 30 people. Did 300 people beat him?". When the action teams shouted hit!, MONO said that his whole body was covered in goosebumps. The sound of negotiations, followed by a series of gunshots, made the scene as breath-throwing as a real battle.
As the smoke from the gun gradually subsided, MONO and the soldiers in the role silently watched each other in the eyes, which was full of tension, but deep down was pride and emotion. He shared that only when he experienced such a close-up experience did he clearly understand the value of the sacrifice and the bravery of the soldiers on the front line.
