The UNSC Carrier Mongoose is a three seater Mongoose that has a little more armor/health then your standard Mongoose but no guns attached to the vehicle, this model is more for a fast quick way to get in and out of places fast or to hide, the Carrier Mongoose is still no match or as popular as the warthog when it comes to 3 seater vehicles but it was inspired by me and my friends constantly having to stack on the 2 seater Mongoose in multiplayer XD
