Requiring an Upgrade

[SuiCidAl-KiSmEt]

I think StealthyDeath probolly know this one, in StarGraft im trieng to have a unit like "Alan Schezar" only to be built during a game, if an Upgrade is researched, Charon Booster (Goliath Upgrade). Does anyone know?

becouse in StarGraft under requirments,units it only show Units and Flags.
I knowtice that for the Zerg Lurker must have

"..... Must have upgrade(next requirment)- Terran Firebat"
If someone does answer this, i bet the upgrade is some unit.
