I made an army of these things with a breeding pen. They were strong enough to kill raptors but when i was busy making a new base my friend did not feed them as requested and they starved to death. I had 5 op turtles and they died. So I continued my “panzer tank” series that was made up of turtles and instead started created an army of allo's so now i have 4 allo's that can kill a rex.
