What are the differences between a submachine gun and a light machine gun, since a light machine gun is a sub?
What is cheaper for the military?

A sub machine gun is defined as a gun shooting pistol cartridges. The two most common are 9x19mm (9mm Luger) and 45 ACP.
And yes, the Thompson is selling for Thirty Three Thousand dollars.
Assault Rifles fire intermedate rifle cartridges such as the 7.62x39 or the 223. They are what is known as selective fire, they can either be fired one shot per pull of the trigger, or as a multi shot (Full Auto). Think of the AK47 or M16.
Light machine guns are designed to be carried by one man. They still fire the assault rifle cartridges, but are generally belt fed and have quick change barrels. Think of the M249.
Medium machine guns are usually fired from a mount, either a ground mount or on a vechile. They can be fired freehand by a single man, but that is not their normal mode of operation. Think of the M60, MG42, 1919a4 or 1919a6.
Heavy machine guns are always mounted. Think of the M2

Uh, no lol. A light machine gun is NOT a sub. Sub-machine guns shoot pistol ammo, aren't designed for sustained fire, and usually aren't designed to be mountable or used with a bipod.
What seperates a light machine gun from a machine gun is that you can walk around with it and use it (even if a bit clumsilly) like an assault rifle.

A light machine gun is not a sub machine gun. The previous poster was right about the sub machine gun firing handgun cartridges.

A sub machine gun normally fires pistol ammunition and light machine guns fire rifle or larger ammunition. The sub would be cheaper but limited in use in a fire fight as it is a short range weapon. Hope this helps. Good luck to youSource(s): First Sergeant, US Army retired
