Starcraft RPG

Do the Zerg in Starcraft 1 have a transport vehicle like the Protoss and Terran do?

I want to build a map that requires transport units and i want to be able to use the Zerg in it. I know the Terran have the Dropship and the Protoss have the Shuttle, but do the zerg have something comparable to those?

1. The Zerg Overlord can get a unit upgrade to allow them to transport units. They can also get upgrades to increase move speed and sight range I believe.
2. yes the zerg overlord it triples its duties as food, detector and transportation. You can upgrade the overlord to have Ventral Sacs (dropship capabilities) after you upgrade a hatchery into a lair you can also upgrade their sight and speed as well
