Find BlackBear Object List in World Builder but didn't find it Options

[hendar94]

Hi. I'm trying make a mission map that involved blackbear and manticore. But i couldn't find blackbear model in the object list. I'm only find manticore model in the object list. If anyone could help me to find blackbear model, what kind of script that i use to reveal blackbear tank and place it on the WB. i'm really appreciate. Also if there is any special script that activate any special add on both of these tanks like warden, shtora, nano bot,etc. that really help me a lot. Thank you in advance.
