Spartan 1332 has landed in equestria,what will he do?

It was a routine drop,drop in kill everyone when suddenly the carrier dose a slipspace jump and Lt.tank claw is pulled in he lands in twilights library and is taken for a faceless mainiac on a mission to fight equestrias "protectors" aka the covenant. Can Lt.Tank be able to defeate the crew of one super carrier?(NOTE:this is my first fanfic so dont judge also i was board so i made this a halo/skyrim/mlp crossover)
