What is the best Halo 3 weapon?

[Dungslayer9]

I want to know what is the best halo weapon vs. Infantry in the campaign mode
Remember to use Range, head shot capability, damage, stopping power, and splash damage

 

[Snuggle]

The best weapon combination would be a shotgun and a sniper. Trust me..
