Alright kiddo, so a combat shotgun is a special kind of gun that is designed for use in battles or fights where the enemy is close by. It's different from a regular shotgun because it can shoot several bullets at once, which makes it very powerful and able to stop bad guys quickly.
When you look at a combat shotgun, you'll notice that it's bigger than a regular hunting shotgun, and it usually has a shorter barrel. This helps to make the gun more accurate when shooting at close range.
The bullets that a combat shotgun uses are called shells, and they are made up of little pellets or balls that come out of the gun all at the same time. When you pull the trigger on a combat shotgun, the gun explodes the shell inside the barrel, sending all of the little balls out at once.
Combat shotguns are used by soldiers and police officers who need to protect themselves and others from dangerous people. When the bad guys see a combat shotgun, they know to stay away because they are very powerful and can really hurt someone.
So there you have it, kiddo. A combat shotgun is a big and powerful gun that can shoot several bullets at once and is used by soldiers and police officers to stop bad guys quickly in close-range battles.
