GSBD: It's Name: Gundam (GINN, No Respawn, S Rank)
With the Earth Alliance '71' path complete it is time to jump over to a new character to start on the Z.A.F.T '71' route starting off with a rather easy mission that is great for getting to grips with the advantages and disadvantages that the GINN has over it's Alliance counterpart, it has far better weapons with acess to the rather powerful Bazooka which has a very high damage special attack, a Machine gun backup main weapon giving it a good option to take out grunt units as well as having a powerful missile sub-weapon that can inflict a lot of damage though needs a short hop on ground missions to avoid the floor, on the downsides it's weapons are all physical meaning it does need to chew through phase shift armour and the lack of a shield means even it has slightly lower effective health and even when guarding it will be taking chip damage.
On the pilot side the Z.A.F.T pilots are forced to have the Coordinator skill locked in, this stat boost that also lets them use any unit without stat loss is utterly terrible for any sort of challenge run as it greatly limits your potential ways to answer problems as well as increasing the time it takes to increase your stats causing a compounding issue in later missions.
For the mission itself there is not much to go over as there are only two sets of two tanks, that haven't learned to aim yet and then two fights with the Strike, one in Launcher and then one in Sword both have easily exploited flaws with the Launcher being very slow and easy to read and the Sword lacking a good ranged attack making it the easiest mission in the game overall.
