Using strictly only a revenant and a brute chopper I present to you: Snagheili Apparition light attack and reconnaissance vehicle.
Detail: Having fought Covenant splinters for almost half a decade Thel Vadam faced shortages of battle worthy vehicles. Usze 'Taham volunteered a solution, salvaging what remains of vehicles he could find and assembling crude, yet bearably sturdy, light vehicles. Although not as powerful and robust as the Ghost, the Apparition was faster. Also, it cost almost nothing to build and was easy to manufacture and maintain. The principle of swamping the enemy with multitudes of cheap, yet reliable, machinery was something he picked up from humans.
