- Main article: Battle of Zulu Alpha
The United Citizen Federation launched an invasion on planet Zulu Alpha. However, the Federation Force was completely defeat by the Arachnids. During the battle, the Arachnids deployed a new breed of Bug as the infiltrator — the Control Bug, but the plan was failed thanks to private Lei Sahara and Captain V.J. Dax.
- The planet could be simply known as "ZA" as Zulu and Alpha are the phonetic alphabets for the letters Z and A respectively.
- For years, the planet has been referred as "Zulu Angel" on the internet. However, digital compositor David Schnee, who worked on visual effect of Starship Troopers 2: Hero of the Federation, identified the planet as "Zulu Alpha".
