It can be implied that they do simply because Aralakh Company appears as a war asset. But Wrex/Wreav brings the bulk of their military might to Earth to support the war against the Reapers. It makes no sense for them to leave their best fighting unit behind.
Well, the sabotage is only discovered if Wrex is the Urdnot leader, and he withdraws his clan's support from Shepard's forces before he confronts Shepard on the Citadel. In that case, Major Kirahee can appear on Earth in Wrex's place. That said, Aralakh Company and the Krogan First Division still appear as valid War Assets, so it's safe to assume that they take part in the battle on Earth even if Wrex withdraws Clan Urdnot from the war.

Ah, so no one on the wiki was that much of a monster to find out? That explains why the question went un-answered. So you can say good-bye to Grunt all the same, and all he mentions is "thanks for getting me out of that tank," even with Wrex withdrawing? RShepard227 (talk)
