Okay revised format(no more silly char jokes):
Kamfer is a good B rank, albeit not having the range of SR's homings or Gouf custom's gattling.
It has a nice wep3, which is a chain mine( whip that does damage but no bullet zero)
Sandrock has a stronger wep3, but lacks the range of the kamfer's chain
thus giving kamfer abit of an edge in meele
now the gouf has a better wep3 due to its bullet zero effect and slighthly shoter range.
Now, on to the skills, kamfer has speed up and assault command, making it a very good unit to charge into the enemy base to hit and run with, then with assault command can boost for a longer duration, making it a very deadly rusher.
Sandrock, however is made for kiting, with the missiles and fortress.Usually, suits with art of fighthing can meele quick but not this suit as SR has a slow meele so it can't really
meele too much or it will die. Fortress cleary does not help, as it makes sandrock slower and not suited to meele(bad combination of skills....)
Gouf custom, however has the most amazing set of skills of these three.
Combine the attack up with Ammo piercing, and u have a very dangerous wep2 that
does additional and increased damage.Seriously, when skill2 activates, the gouf custom will start to show it's good points and be a deadly force to be reckoned with.
