- The triangle formation is a military tactic employed by reeeeeally smart Transformers!
When you've got three military jets to play with, it's hard to know how you're supposed to arrange them all. Do you put them in a straight line? Send them in opposite directions? Tie them into a big bow tie? Crash them into each other?
Fortunately, countless years of warfare and a military doctrine which emphasizes air superiority have enabled the Decepticons to uncover what may be the ultimate in three-man formation flying: the triangle formation. Consisting of one jet with two jets nearby (above or below and/or possibly behind), the triangle formation allows all three participants to fire on a target at the same time, and not crash into each other. Ground-breaking!
Dreamwave Generation One comic continuity
Fear the triangle, baby. That's why Starscream is Air Commander.
Seriously, there's like, no other reason for Megatron to keep him around.
Cybertron cartoon continuity
The Cybertron Defense Team makes use of a stunningly genius variant of the triangle, by forming a triangle around their opponent (in this case, the Gigantion rebel Menasor) and then shooting inward all at the same time with all the might of their
stock footage integrated weaponry.
Surrounding one's opponent? BRILLIANT!!!
