None of the BTB maps have scorpion tanks! It’s been this way ever since launch, and yeah, you heard it right:
BTB has NO tanks.
What atrocity this is! Why have no one implemented them back yet? Currently there is no way for you to drive a scorpion in matchmaking.
What is Halo BTB without tanks…
At least we’ll have Warzone for tank fun 
The only maps I can think of that has tanks are Containment, Terminal, and Blood Gulch when it’s Team Slayer. So yeah, there is a serious shortage of tanks.
@AKA RED GLORY - You are quite right, I’ve managed to get the scorpions on Containment (CTF) and Blood Gulch (CTF), and the wraith on Terminal (Team Slayer). However, you forgot about Halo 4… there are scorpions on Longbow for Team Slayer.
Once the next update drops, there will be 8 v 8 dominion on Halo 4… I hope there will be wraith tanks available on Exile and Vortex. As for Longbow, hopefully the scorpion tank will be there too.

Longbow (H4) has BTB tanks in all but the CTF gametypes; and I’m certain there are Halo: CE tanks for BTB (Blood Gulch?), because I keep getting sniped out of them.
