Andy Stumpf, a former US Navy SEAL, discusses the realism of underwater action scenes in movies. He emphasizes that while some elements, such as the use of SEAL Delivery Vehicles (SDVs) and the importance of stealth and speed, are accurate, others are not. For example, he points out that it's unlikely to encounter a shark or any other large creatures while swimming, and that divers would not typically use buddy breathing as a lifesaving measure. He also clarifies that diving at depths of less than 20 feet, as depicted in some movies, is not typical for SEALs, who often dive at night and at greater depths. Stumpf stresses the importance of safety procedures and equipment, and that real-life underwater operations are focused on getting from point A to point B efficiently and stealthily.
1. The speaker, Andy Stumpf, has spent 17 years as a US Navy SEAL and hosts the "Cleared Hot" podcast.
2. The podcast episode discusses the realism of underwater action scenes in movies.
3. Stumpf mentions that he has never seen anyone give an audible brief on an airplane due to the noise.
4. He emphasizes the importance of cutting away from your parachute before you hit the water, as doing so at lower altitudes can be dangerous.
5. Stumpf explains that the type of diving done by SEAL teams is focused on getting from point A to point B, often for implanting charges or sensors.
6. He points out that most of the diving he did was at night and at depths less than 20 feet.
7. Stumpf mentions that the suppressor on a rifle reduces the decibel output, allowing bullets to fly through the air without making a cracking sound.
8. He states that the SEAL Delivery Vehicle (SDV) is a miniature submarine used for moving people and equipment over long distances.
9. Stumpf explains that the back strap of a dive fin is usually taped to the diver's leg, and fins are necessary for swimming or exerting oneself in the water.
10. He also clarifies that SEALs do not use tridents or spears and are not designed to fight in the water.
11. Stumpf mentions that the M203 grenade launcher can be fired underwater, but not in the continuous propellant mode seen in the movie.
12. He explains that diving is done in pairs, with one person handling the navigation board.
13. Stumpf states that communication underwater is often done through hand signals, grease pencils, and plastic pieces, or by squeezing or blabbing.
14. He warns that if something goes wrong during a dive, the first thing to do is to stop the dive and surface.
15. Stumpf mentions that buddy breathing, sharing one apparatus between two people, can occur underwater, but it requires working together and following procedures.
