GURENGE are rare flamethrower armed MTs in LR that are low to the ground and thus are difficult targets to some bladers.
ZEKUH helicopters are used since AC3, they can actually be hired as consorts to some missions.
AMIDA made appearance in NX as prototype biological weapons and later in LR as pests that the player is hired to exterminate.
RUSYANA (盧舎那) = "Cosmic" Buddha.
GURENGE (紅蓮)
ZEKUH (是空)
AMIDA (啊瞇大) = From words Amitabha (Infinite light) and Amitayus (Unlimited life force), aspects of deity AMIDA.
Not all of the names are of Japanese origin, some are even those of Thai, Tibetan, Indian, or Chinese origin. And yes, all terms related in a way to Buddhism.
