I think the Juno units have the most unique arsenal when compare to terra units and vapos units.
Juno moas carry I think 4 different types of gun and three of them are disc launcher, rocket launcher, and glaxion.
Juno comba units also having only 3 weapon types, carry a hammer&shield, a swarmer rifle, and a convectrix.
Juno crewmans, from small pistol to modified supra with explosive bolts.
Juno tech's exegris's infinite magazine full auto blasts and artic juno exmus's glaxion and frost aura.
Juno malleus machinist with large hammer is basically the new version of prod crewman.
