Comanche calls in 1 mini helis when bloons have first reached 25% of the track.

Comanche calls in 2 mini helis when bloons have first reached 50% of the track.

Comanche calls in 3 mini helis when bloons have first reached 75% of the track.

If any of the mini helis are already on screen they get their duration refreshed instead and remain on screen. (can be interpreted as Comanches leave when the latest Comanche spawn runs out of time)

Overall, you can spawn 6 Helis in a round if you use it properly, but if not you may just get Comanches that remain on screen for longer.
