When in the water the railgun seems lighter and more maneuverable than a standard gun because the barrel to spear ratio is greater and the internal diameter of the barrel is also larger, therefore giving it more buoyancy. The front of a standard gun is always heavier because the spear protrudes further beyond the muzzle. Some try to compensate by adding a foam piece to create lift.
This does work but increases the end profile of the gun making it more difficult to maneuver. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
