Kelos'vaarda-pattern storm rifle

The Type-55 Directed Energy Rifle/Advanced (T55 DER/A), commonly known as the Storm rifle, is a Sangheili directed energy weapon.

History
Designed by Lodam Armory in the wake of the Great Schism, the T55 saw use during Sangheili civil conflicts following the Human-Covenant War's conclusion. The T55 DER/A is considered to be a successor to the widely used Type-25 Directed Energy Rifle; however, it is more similar to the Type-51 Directed Energy Rifle/Improved, itself an upgrade of the T25, in both form and function. The weapon features such modifications as a modular coil set, a high-mounted cooling shroud, and an extended barrel.

Speculation
The "Storm" in the weapon's name suggests that it was created for, or is used predominantly by the Storm, a remnant faction loyal to the ideals of the Covenant. However, Lodam Armory co-manufactures matériel, (namely the Type-32 Ghost), alongside Iruiru Armory, which is located in Yermo and is thus presumably allied with the State of Vadam. Assuming Kaidon Thel 'Vadam still holds sway in the region, it is unlikely that he would allow dealings with Covenant loyalists; this implies that the weapons are either widely used and distributed or were stolen by Storm insurgents.
