Submarines utilize several forces to navigate underwater, primarily buoyancy and hydrodynamics. Buoyancy allows them to control their depth by adjusting the amount of water in their ballast tanks, making them either sink or rise. Additionally, hydrodynamic forces come into play as the submarine moves through the water, influencing its speed and maneuverability. Propulsion is typically provided by diesel-electric engines or nuclear power, enabling the submarine to travel silently and efficiently.
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
submarines and bats both use sonar. Calvin was here
oceanographers use submarines to take pictures of sea life and things that have been found or things that they are looking for.
The marines do not use submarines. Only the Navy does.
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
As far as civilian submarines, technically no, as tourist submarines aren't actually transporting from point A to point B. For military submarines, absolutely. People using submarines as transport vessels are Special Forces (e.g., SEAL's), Navy research scientists (Polar Expeditions), and other individuals designated as required.
A tactic used in an attempt to cut off supply lines to Japanese forces was the use of submarines. By sinking their ships before they could reach troops, it severely limited their fighting abilities.

The Germans were the first to use Submarines in World War 1. Now i believe that the marines now do at times.
Sinking ships; exploring the depths.
For eating ;)
Yes, they did.
