Start the mission by fanning out all five rounds towards the teal tank directly opposite you. In the above video, I didn’t execute this very well with a fan that is too narrow. But still, it was wide enough to have the effect of trapping it into a corner (see General Strategy against Teal Tanks). Whatever the case, be cautious of your own shells rebounding from the far wall!
The rest of this mission can be carried out following the General Strategy against Teal Tanks
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.
Here is a level that can be either very easy (depending on your luck), or deadly if you’re not lucky with the yellow tanks. In the video above I was, you guessed it, lucky.
This level is completed basically using lots of fan and rebound shots. For most levels using this block layout, I usually fire a fan-and-rebound to the bottom wall first, in attempt to hit the tanks in the lower right quadrant. This may or may not succeed, but it has an equally important effect – it prevents those tanks from entering your quadrant. Speaking of which, that is usually what the tanks in the upper left quadrant will have done by this time.
When the tanks from the upper left quadrant has entered or are entering your quadrant, some of your previously fired shells should have expended themselves, leaving you new rounds for defense. Use the usual tactics of leading and fan-and-rebound from then on.
Be patient and avoid the two upper quadrants altogether, as in the heat of battle, the yellow tanks can lay mines behind the two triagular barricades unbeknownst to you. Obviously that’s dangerous. When you are left with tanks in these quadrants who aren’t willing to come down, use fan-and-rebound shots to get at them.
OK it really took 11 seconds. But it sounds cooler to say “Mission 10 in 10 seconds” This mission introduces the red tank, which rapid-fires ordinary shells (i.e. rebound once).
As the mission begins, I generally move to the lower center of the battlefield, firing two shells up the center-left corridor on the way. These two shots will sometimes take out the tank that started out at the top center of the battlefield, but which almost invariably move to the corridor as the mission begins, running into those two shots.
With just two red tanks and many high-rising barricades, the general tactic in this mission is to stay in the lower center where you can see things clearly, and duel with these tanks at short distance (see General Strategy against Red Tanks). If the above tactic did not take out the first red tank, you would bascically do the following twice: stick to the lower-center barricade near either end where the red tank is anticipated to emerge, paying attention to the enemy fire that will be rebounding (from the bottom) literally left and right. Then, as soon as the red tank emerges, move up close and begin your duel! As explained in the General Strategy against Red Tanks, this actually carries little risk
