I served in the US Navy as a submariner. No one can convince me that the Soviet navy is as inept as they're portrayed here. Ex-captain has an almost fatherly regard for his men (implying that they've served together for a long time)yet in every drill and real disaster, men collide head-on, cut their hands on a chain-fall, spill fuel on the deck (conveniently forget to dispose of it which sparks a conflagration later, and largely act like oversized teenagers at sea for their first trip. The cook is always caught juggling plates of spilling food. The doctor repeatedly, comically, drops the same medicine again and again.I could go on. The captain never would have left the control room to hide in his cabin to have a hissy-fit. Their individual bravery was probably the most accurate part. Unrealistic, appalling, unbelievable, insulting to all submariners.
