Cheating in Warzone Assault

I’ve ran into a few people that are cheating in Warzone Assault. The use a warthog to glitch into the wall on Array when the attacking team is attempting to take the Armory. Since they are in the wall, nothing can damage them and they are able to prevent the attackers from capturing the base. This basically guarantees that the defending team will win, since the attackers can no longer take the base without glitching into the wall themselves.
