Missions will be assigned in split categories depending on the rank, for example
D-ranked pilots will receive missions from their mentors, as they are not really qualified pilots to take missions from higher orders.Usually their missions will consist of delivery, and an occasional celebrity escort, but nothing else.
C-ranked pilots will have evolved from being mentored, and will be receiving their missions from military leaders. Their missions will mostly consist of back up, money transport.
B-rank pilots have made their way almost halfway up the chain of command, and listen on to A-ranked pilots.Their missions reside from raiding enemy bases, capturing mobile suits, and destroying gundams.
A-ranked pilots receive their missions from the president only, they are usually sent on rescue missions, capturing gundams, and leading an army into battle.
S-Ranked pilots answer only to themselves sending themselves on their own missions.
Z-ranked is the same as S, but stats are not maxed out.
