If it is about reality, I can provide some (I prepared a summer vacation to write my final paper)

Guns: Type 54 pistol, Type 92 pistol, Type 95 rifle, Type 95 light machine gun, Type 79 submachine gun, Type 03 submachine gun, Type 97 explosion-proof shotgun and Type 88 sniper rifle (if the story is in China, these are enough, they are all guns in active service, of course, Type 54 is retired) M 16, M4A65438. MP5, UZI, MP5K, P90, these are all good submachine guns; M 10 14, Remington M870, these are all good shotguns; AWM, SVD and M82 are all good sniper rifles. M60, M249, MG3, M 134 These are very good machine guns.

Melee weapons: military dagger, triangular army thorn, Damascus machete, tiger tooth saber.

Heavy firepower: RPG-7, AT-4. These are rocket launchers.

Basically, these weapons are enough, one hand, hope to adopt.

Ps: Please don't copy and paste every time you practice.
