From the observation point of view, the radar soldiers kept watch in the distance, and realized that the warm altitude in winter was more than 4500 meters along the Tuotuo River, and the snow on the winter solstice had not yet penetrated. At a radar station of the Air Force of the Western Warfare Zone stationed at the source of the Yangtze River, the rising sun slowly leaped out of the ridge, giving a dazzling halo to the five-star red flag flying over the camp. It has been assigned to this plateau radar station for more than a year. On the morning of the winter solstice, Lieutenant Platoon Leader Liu Tao ended his first "solo duty". Pushing open the gate of the duty room of the position, he could not help closing his eyes with a flash of sunlight coming at him. A sense of satisfaction with sweet taste rushed into his heart. Last spring, the assessment of duty qualification for solo duty was like a mountain in front of the new platoon leader Liu Tao. "Come on, you are a graduate of radar major." In fact, there is no need for Hu Bin, the head of radar station, to be a "fierce general". Liu Tao has already had a crush on himself. During the day, he learned to deal with the situation in the position command room. At noon, he followed the veterans to get familiar with the operation. At night, he repeatedly memorized the process in the study room... until he successfully passed the independent examination six months later, Liu Tao said, his excitement was comparable to the moment when he got the admission notice of the military academy. However, passing the examination alone is different from being on duty alone, just like the difference between getting a driver's license and driving on the road for the first time. The snowflakes fluttered all night, and the tension caused by various complicated air situations also lasted all night. After completing the duty task independently, Liu Tao, who was "flying alone" for the first time, really understood what the confidence and confidence of the radar soldiers that Hu stationmaster said meant. To guard the sky for the motherland, radar soldiers must be competent for their missions. The true understanding of the mission has also become the reason why successive officers and soldiers stationed in radar stations stick to the plateau without regret. From Hu Bin in his youth to Liu Tao today, this is also the spirit forged in the blood of officers and soldiers in the radar station. Sticking to the plateau is not only the mission of lovers, but also their faith in the hearts of many radar soldiers' families. As Liu Tao said, the person who knows himself best in the world is not only his comrades in arms, but also his wife Chen Simin. The two were high school classmates. After Liu Tao graduated from university, they went to get their marriage certificates. Having been stationed at the radar station for nearly 2 years, the little couple has not had a wedding yet. The new military sister-in-law, who was a primary school teacher in her hometown, became the strongest backing for her husband. It is also the company of "being far away and near" that keeps their hearts bathed in the warm sun and makes them miss each other. The husband is busy practicing "solo flight", so he has less phone calls in the past six months. On the eve of the winter solstice, a letter and a large package of "promoting teachers and asking questions" started from their hometown in Sichuan and flew to the Tuotuo River. Opening the package, it turned out that there were several cans of red chili sauce carefully prepared. Liu Tao and his comrades in arms couldn't help laughing. Many of them are from their hometown in Hubei, Sichuan Province. These chili sauces are really "sent to everyone's heart". "You have been a little skinny recently. Chili sauce is good to eat, and you will be fined one more bowl of rice every day. You will not gain five kilograms before the Spring Festival, and you will not be allowed to see my face..." Liu Tao holds the letter written by his wife, and reads it word by word with his hometown "Trump". The air is full of love, but also full of nostalgia, which makes the obedient comrades in arms laugh
