I don't think you can get that e-tank without glitches after Phantoon is dead, however if you can decipher this:
DMantra> froze enemy in the right spot to kneel-jump up. which ran the risk of perma-stuck if i killed it. but i managed to freeze it again and get out
then you can perform the glitch to get in there, get it, and get out.
Before Phantoon it's a lot easier to get since the passage directly under it is open.
