From Halopedia, the Halo wiki
The Covenant and its splinter factions use a wide variety of weapons. Like most Covenant technology, their weapons are highly exotic in both operation and design, especially in comparison to the human arsenal. Covenant weapons exist effectively for every usage niche, ranging from close-quarters combat weapons such as the Sangheili's emblematic energy sword to space warfare armaments capable of striking across thousands of kilometers, such as plasma torpedoes and energy projectors. Many examples of the Covenant arsenal are directed-energy weapons, typically utilizing either plasma or particle beams, and run off a battery charge. However, some Covenant weapons also use physical projectiles, such as the Type-51 carbine or the Type-33 fuel rod gun; additionally, most weapons of native Jiralhanae design fire projectiles rather than energy.
