The flamethrower is already there, but I had to put something to fill the hole and I thought this picture looked cool so I used it.

Updated:

_Grenade launcher added to the rifle (use the pie menu to replace the flamethrower with the GL, hold num1 to aim, release to shoot)
_New HEAT rocket for the launcher
_The incendiary rocket now causes weak explosive damage, and its area of effect has been increased a bit.
_Some minor adjustments.

And here is a video of the grenade launcher:


Edit: You can shoot the grenades in mid air to make them prematurely detonate, also these will bounce off ground, and explode when near an actor. When you hold the grenade key a trajectory guide appears, release to fire.

So first off this is an awesome mod, very nice job Mehman. The only thing that frustrates me is the inability to use the pie menu buttons for both the rifle and rocket launcher leaving me to use the keypad often getting me killed in combat. Another issue is not being able to use the artillery strike function of the rifle plus there is no error indicated on the console when opened. Other than that the rest of it works fine.

You can swich ammos by using the pie menu, if you can't that means you don't have the last version, also to use the artillery strike you must have artillery deployed.

Alright, to clear it up i do have the latest version. I tried the artillery and it works fine, I still have the issue of the pie menu, all i see for the buttons are red squares even for the rocket launcher(Incendiary, EMP, Frag and HEAT rockets) and the rifle(AR, HE, EMP ammo and GL attachable).

It seems that you are using B25 instead of B26. In B25 the custom pie menu was broken and it only displayed red squares.

Damn i thought i had B26. Well this ruins fun

There are two download links in the OP right now.

Corrected.

Bullets don't change for me for some reason
After using the pie menu, I reload and shoot the same bullets as before

Any lua errors? What CC version are you using? Does it do that every time or only when you're doing something in particular? What OS are you using?

No Lua errors, using CC26 on Windows XP
Rocket's change fine, but bullets don't

That's really wierd since they both work on exactly the same principle. I'll look into it but I cant guarantee anything.

After some research I have found that the Pie menu buttons do not work on the rifle
Numpad seems to work fine

They work for me. Did you edit any file or something?
