In the deep winter season, a submarine of a certain naval submarine detachment conducted practical training in a certain sea area. During the task gap, the "Far Voyage Classroom" with the theme of "Loyalty to Mission, Forging a Underwater Vanguard" was held in the deep sea. Regardless of facing difficult opponents or encountering complex sea conditions, we must not fear difficulties and face challenges to ensure the successful completion of the mission... "The crew members discussed and exchanged their experiences on the mission, further strengthening their confidence in achieving success in their positions. Undercover the deep sea, sharpen your sword deep blue, and wherever the mission is executed, the classroom extends. ”The leader of the detachment introduced that due to the heavy training tasks of the detachment, submarine soldiers often patrol the deep sea and ocean for long periods of time, which brings many challenges to the detachment's concentrated ideological and political education. In response to the practical problems of difficulty in providing educational venues, concentrating personnel, and synchronizing time during submarine voyages, in recent years, they have increased their efforts in "dynamic education, scattered education, and self-directed learning". Combined with the actual training and preparation of officers and soldiers, they have opened "long-distance classrooms" and carried out random education at every opportunity, embedding ideological and political education into frontline combat positions and integrating it into the entire mission process; Through forms such as broadcasting newsletters, educational micro lessons, and story sharing sessions, the "Far Voyage Classroom" is down-to-earth, popular, and lively, inspiring officers and soldiers to maintain a strong sense of victory. In practice, the detachment emphasizes the role of officers and soldiers as the main body, encourages everyone to take the stage and sing the lead, and combines activities such as "cabin innovation and job competition" to guide everyone to tell exemplary stories, share training experiences, and create a strong atmosphere of learning from others and striving for excellence. During a mission, a submarine of the squadron experienced a sudden malfunction in its seawater pump while diving. The crew quickly completed operations such as plugging and draining the water to ensure the smooth progress of the mission. The next day, the captain of the crew and the diesel engine technician stepped onto the podium of the "Far Voyage Classroom". In the face of danger, everyone worked closely together and efficiently dealt with it, demonstrating the good style of submarine soldiers' 'one hundred people wielding one gun'... "In class, they shared their feelings and insights on emergency troubleshooting, which resonated with everyone. The leader of the detachment introduced that they have taken the "long-distance classroom" as a starting point to focus on ideological and political education under the conditions of mobilization and dispersion in major tasks such as training exercises and long-distance patrols, effectively stimulating the enthusiasm of officers and soldiers for military training and preparation. Not long ago, a submarine of the detachment conducted live fire training in unfamiliar and complex waters. During the task gap, they organized a "long-distance classroom" with the theme of "Remembering the turbulent years and discussing underwater inheritance", leading the crew to collectively revisit the struggles and fine traditions of the older generation of submarine soldiers. Encouraged by the spirit of our predecessors, the determination and will of officers and soldiers to fearlessly face difficulties and charge forward have become even stronger, and the performance of weapons and equipment has been effectively tested in live fire training.
