This mission is engaged, if you’re not very passive, by first taking position either at the top or bottom of the left wall. By habit I usually take the bottom first. Sometimes, you can take out the teal tank near the lower right corner by trapping it into a corner (see General Strategy against Teal Tanks). Unfortunately for me, I didn’t execute the trap very well (in particular, since one of my initial five rounds were canceled out by the teal tank’s rocket-propelled shell, I could have followed up with one more to increase coverage of my shells), and the teal tank had enough room in the corner to evade my shells. And then I was hit.
From then on, it is mostly fan-and-rebounds. See also Overall Strategy for Yellow Tanks.
