"You know, it looks delicate and so you feel like you need to hold it kinda gingerly—but then you see an Elite crack a Bravo Kilo's head with one—the things are built tough."
— Anonymous UNSC serviceman[2]

The Okarda'phaa-pattern Rifle[4] (UNSC Type classification: Type-25 Directed Energy Rifle, T-25 DER),[2][5] more commonly known as the plasma rifle or plasma gun, is a fully automatic rifle, formerly serving as a Covenant infantry weapon. The Type-25 DER was the primary weapon of the Covenant's officer corps,[2] standard issue to Sangheili and Jiralhanae. However, lower-caste species within the Covenant who had attained significant rank within the Covenant military were also issued this weapon during operations. The Type-25 DER was one of the earliest and most frequently encountered Covenant plasma weapons. It occupies a role very similar to the human assault rifle.[5]

The earliest iterations of the plasma rifle have been in use by the Sangheili warrior class for several millennia as of the 26th century and were in service long before the Covenant itself was established. Human researchers of the UNSC's Office of Naval Intelligence believe that the plasma rifle's current design dates back at least five hundred years, with only slight modifications made to the rifle over time.[3] In the post-Covenant War era, though, it has been largely phased out for the Kelos'vaarda-pattern storm rifle.[6]
