Military-themed film clears air on online controversy

Yang Gang, the military consultant for the film and a retired submarine captain, said he could resonate with and understand the scene. He explained that the captain had just ordered the closure of a compartment on fire, a decision that might result in the sacrifice of several crew members. At such a moment, the captain would need unwavering belief to make the tough decision and accept the consequences.

Yang, who served on a submarine for over 30 years, including eight years as captain, explained that submarine crews are among the military's most psychologically tested troops.

"The internal space of a submarine is cramped, with high humidity and temperatures. The sailors not only have to constantly monitor the equipment but also endure the isolation of being cut off from the outside world for extended periods. Every mission is a life-and-death test," he explained.

Wang Qiang, one of the producers in charge of military knowledge, added, "In the working environment of submarine soldiers, torpedoes are stored just nearby, along with oxygen tanks, chemical agents, and other dangerous materials in a confined space. The living conditions are harsh and perilous."
