In March, in northern China, the spring atmosphere gradually intensifies. The car that the journalist and his team were riding in finally arrived at the camp of a certain ammunition technology team of the Northern Theater Command Navy, bouncing and circling along the mountain road. Entering the camp gate, two tall and lush coniferous pine trees came into view. These two green pine trees are our 'unity tree' and 'centripetal tree', as well as a witness to the successive officers and soldiers rooting in the deep mountains, inheriting and promoting the 'Foolish Old Spirit' of the new era. "Instructor Chen of the technical team told reporters that the technical team camp is located in a dense forest in the deep mountains, with harsh natural environment and difficult living conditions. For over 70 years, generations of officers and soldiers have rooted themselves in the deep mountains, willingly serving as "Foolish Old Men", using their youth and passion to efficiently complete their assigned security tasks, ensuring the safety of the storage area without accidents. In recent years, with the care and concern at all levels, our living conditions have been getting better and better. ”Standing under two green pine trees, Instructor Chen pointed to the scattered barracks around him and told reporters that in the past, the infrastructure was backward, the signal in the mountains was poor, and it was difficult to get water; Nowadays, the camp has not only access to running water, but also renovated the playground, built a "Deep Blue Book Bar", sauna room, therapy room... With a whistle, several soldiers dressed neatly gathered in front of the barracks. This is the soldiers going to patrol the mountain. After obtaining consent, the reporter followed the team to set off together. After leaving the camp, all the reporter could see were rolling mountains and lush pine trees. A gentle breeze blows, causing pine branches to sway and make rustling sounds. Isn't the scenery good? When I first arrived, I also thought the mountains were beautiful, but over time, I became a little tired. ”The reporter turned his head and heard Sergeant Du Tianyu speaking. Being a soldier was my childhood dream. When I first put on my military uniform, my mind was filled with the longing to gallop across the ocean and fight against the winds and waves. When we arrived at the technical team, we realized that we were a 'land navy', without warships galloping or rough seas. Every day, besides ammunition support, we patrolled along the mountains. The passion we had at the beginning of joining the army gradually cooled down. ”Du Tianyu said that many of his comrades around him have gone through similar emotional journeys. The class monitor Liu Huibo quickly noticed Du Tianyu's ideological fluctuations and took the initiative to form a team with him. Whenever he had free time, he would tell him stories about the unity and hard work of his predecessors. A gun maintenance, the task area is not far from the two green pine trees in the camp. Seeing that Du Tianyu was somewhat absent-minded, Liu Huibo pointed to two green pine trees and said, "Look at these pine trees, if you want to grow strong, you must firmly root them bit by bit. Human growth is no different from green pine trees." Liu Huibo told Du Tianyu that many years ago, the senior members of the technical team built the "1.0 version" of the camp in the mountains with their own hands and shoulders. In order to commemorate the spirit of unity, struggle, and perseverance of the 'Foolish Old Man', they planted these two green pine trees in the camp, named 'Unity' and 'Centripetal' respectively, and have grown until today. Seeing Du Tianyu lost in thought, Liu Huibo said earnestly, "Nowadays, conditions are getting better and better, but the hardworking spirit and perseverance of 'Yu Gong' cannot be lost at all." "The stories of my predecessors deeply touched me, and a mission I went through later strengthened my belief in rooting myself in the deep mountains and achieving success in my post. ”Du Tianyu said that at that time, a certain warship received a temporary sea mission and needed emergency ammunition supply. That day, from dawn until nightfall when the moon was high in the sky, he and his comrades transported ammunition box by box without even taking a sip of water. At the end of the mission, he felt his throat dry and smoking, and many of his comrades lost their voices. That day, I was exhausted to the limit, but I also truly understood the meaning of perseverance. ”Recalling that mission, Du Tianyu couldn't hide his excitement. "Although we couldn't gallop across the ocean, every ammunition on the warship condensed our hard work." Unconsciously, the mountain road became narrower and the slope became steeper. This road has become much easier than before, "said Instructor Chen, seeing the reporter walking cautiously. In recent years, the higher authorities have continuously strengthened hardware construction, the security equipment of the technical team has become increasingly advanced, and the means of duty have become more diverse. The ability to fulfill mission tasks has also skyrocketed. Technology is becoming increasingly advanced, and surveillance can achieve full coverage of the camp. Why do we still need to organize officers and soldiers for on-site patrols? ”The reporter gasped heavily while questioning. With the 'Thousand Mile Eye', don't lose the 'Iron Foot'. ”Instructor Chen said that the technical team has long been equipped with technological means such as drones and fire control gimbals, but the safety requirements for the materials stored in the warehouse area are extremely high, and no mistakes are allowed. On site patrols by officers and soldiers can identify blind spots that are difficult to cover with surveillance, adding a "safety net" to the warehouse area. Speaking of which, Instructor Chen told the reporter another story. During a mountain patrol, Sergeant Wang Qingwei suddenly smelled a smell of smoke drifting down the mountain. As the location was close to a cave, Wang Qingwei and his comrades ran down the mountain. After investigation, it was found that the smoke from cooking at the foot of the mountain had drifted up along the wind. Although it was a 'wrong' incident, the storage area bears the responsibility of safeguarding the safety of a large amount of ammunition. In case of danger, it is better to make mistakes than to miss them. ”Instructor Chen said, "After serving in the military for a long time, officers and soldiers treat the warehouse area as their home to guard. Guarding the warehouse is guarding their home, and guarding their home is guarding their country." On the way back to the camp, patrolling officers and soldiers told reporters that they did a big thing last year - to maintain and upkeep the firearms participating in the 93 military parade. Thousands of firearms need to be wiped and maintained one by one, carefully cleaning the fine residue inside the air vents, and dismantling every part that has been eroded by wind, sun, sweat, and dust... Looking back on this experience, Du Tianyu's pride and honor are overflowing: "Watching the firearms that have been proudly reviewed in his hands is completely new, no matter how hard it is, it is worth it!" Inspired by the "Foolish Old Spirit", successive technical team officers and soldiers have worked hard and continued to charge forward, forging a strong team that "forges the original intention of thinking, cultivates the original spirit, demonstrates their true colors in daily practice, and inherits and empowers the bloodline". He has won the collective third class merit three times, and the party branch has been rated as an advanced party branch by superiors for 17 consecutive years. On the way down the mountain, the wind is gentle and the flowers are fragrant. Looking around, the two tall and straight green pine trees in the camp resemble the simple and unadorned soldiers rooted in the deep mountains. The reporter knows that when the warship chops through the waves in the deep blue sea, they will once again set foot on the patrol path... (Xinhua News Agency)
