In the face of new positions and challenges, it is better to assume responsibility for war rather than worry about it. What is it like? A few years ago, Tang Changsheng could only answer one sentence: "War is a contest between blood and skill." Today, he can outline many answers in his mind. Before arriving at the guidance and evaluation center of a naval joint training base, Tang Changsheng was a "top amphibious soldier" in the Marine Corps. "Crossing beaches and seas, wading across rivers and marshes is a daily state for marines, and Tang Changsheng likes the feeling of fighting.". After transferring to become a director and dispatcher, Tang Changsheng felt that he was experiencing an unprecedented battle - in the past, carrying out tasks with a small team, there were still many tactics to learn and many skills to practice; Today, what are the challenges of participating in organizing joint training for multiple services and arms? In this regard, the engineer Yu Zhou is full of expectations. This bespectacled, seemingly capable officer studied automation, control engineering, and other majors before pursuing a PhD in electrical engineering. After arriving at the center, he was mainly responsible for data collection and evaluation. Taking up his new position, he said to himself, "Analysts who don't want to fight are not good analysts!" Like Tang Changsheng and Yu Zhou, most of the officers and soldiers in the center have been transferred from other majors. One part is transferred from subordinate units of the base, and the other part is from troops such as surface ships, aviation forces, and coastal defense forces. "The sky, the sea, and the shore are all gathered together." Someone joked, "The 'union' of the joint training base is first reflected in our personnel roster." Worry, longing, contemplation, and exploration... The tide of the times has brought this group of young officers and soldiers together. In the eyes of Liu Xiaoran, the director of the center, everyone has different majors and experiences, but one thing is the same: "We are all candidates for the exam." Regarding the exam, Liu Xiaoran has his own understanding: A ship sailing to unfamiliar waters often requires a group of brave sailors; Today, troops are constantly breaking into the "strange waters" of combat effectiveness construction, and they also need a group of brave pathfinders. Liu Xiaoran was recruited from a local university and initially assigned to a frigate detachment. He boarded multiple types of ships and held positions in various departments such as aviation, navigation, and weapons. Later, he was transferred to the base as a training staff officer. Now, he has become the head of the newly established guidance and evaluation center. "In the face of new positions and challenges, it's better to take on responsibilities rather than worry." At the forum, Liu Xiaoran shared his experiences of several transformations, and his comrades nodded thoughtfully. During the exchange of words and phrases, it was found that most of the officers and soldiers selected to work in the center had studied multiple different majors and experienced various positions. Whether this is a coincidence or a deliberate arrangement by superiors is unknown to officers and soldiers. Liu Xiaoran quoted a popular phrase from social networks, saying that everyone with multiple skills and multiple tags is a veritable "slash youth", causing everyone to laugh. In a relaxed and warm atmosphere, Liu Xiaoran said meaningfully, "If you surround enough slashes together, you can form a complete circle." "We young people with 'slashes' need to form a new dream fulfillment team," Liu Xiaoran said. "The sea is still the sea, but the content we see is completely different. Joint training is being conducted, and the troops are
