galat titans are gigantic mechs with armor made of steel. they take a crew of 5 (4 gunners, 1 pilot) to operate. because of their thick armor, they are also nearly indestructible (unless heavy weapons are used and i mean really heavy weapons like missiles or bombs and orbital weapons) their fists are rocket propelled as well, adding even more force.
for my nation in rmg also the reason there is only one pilot needed is because pretty much everything (except the turrets and obviously pilot) is manned by worker bots. they are also pretty big, the size of a skyscraper pretty much and those anti aircraft turrets are strong as well
