If the player gets a "Super Robot Wave" in Garden Ops, composed of 3 Mech Gargantuar boss icons, then Robo-Zombies and some Computer Scientists will back up the bosses, making up the entirety of super boss wave.
Robo-Zombies also have their own special wave, called "Robo-Assault."
Strategy
The best case scenario for dealing with this character is to use a character with range, such as Cactus and her variants. Use higher ground and attack it, as its ranged attacks can be easily dodged and its melee attacks will be incapable of damaging you.

Trivia
Despite being different than a Foot Soldier and sharing none of the Foot Soldier's abilities, it appears in the "Soldier" wave in the Flag of Power.
This may be because it shares several visual aspects with the Foot Soldier, such as the helmet and the rocket pack on it's back.
It also has a military mark on its arms signifying that it is a corporal.
Robo-Zombies have their own unique icon in the full game, although in the Beta they shared their icon with the Foot Soldier.
In the Beta it only gave the player the XP for a "Vanquished Zombie," but in the full game it gives them the XP for a "Vanquished Zombie Hero".
Robo-Zombies cannot be swallowed or eaten in any way by the Chomper. If you attempt to eat them from the back or front, they simply spin, like when they use the Heavy Punch, and if you try to eat them from below with burrow, they keep your mouth open with both metal feet with both hands on their hips, chuckling and looking forward.
In both cases, you still have to wait a few seconds for the Chomper to chew and digest, despite not having eaten anything. This happens with some other zombies in the original Garden Warfare and Garden Warfare 2, and is likely a developer oversight.
Despite being entirely robotic, they can still be turned into a Stinky Goat with Goatify.
Despite having a rocket pack with rockets on their back, they never actually use it to jump high or fire rockets at you.
However, in the cutscene in the Agent Citron mission "Showdown," the Champion Robo-Zombie who guards the key points the rockets on its back at you. After the cutscene ends, the rockets are facing upwards again.
