Ace Combat: The Equestrian War/Awesome

Firefly's Dynamic Entry in chapter 2.
In chapter 3, Lightning Bolt performs her first Shining Spark and defeats two griffins with it.
Mobius' inital appearance in chapter 7.
By the end of chapter 9, Twilight, Pinkie Pie, Applejack, Rarity, the ponies from Mirage squadron, the Wonderbolts and Cutie Mark Crusaders all sing "Gotta Stay Fly" from Ace Combat: Assault Horizon (with slightly changed lyrics) and the entire ballroom (yes, even the noble ponies!) cheers on them and applauds their performance.
Rainbow Dash performs a Sonic Rainboom to break inside The Burning Talon in chapter 10.
Scootaloo and Sweetie Belle, of all ponies, get one in chapter 11. They use a home-build catapult to help defend Ponyville from the griffin attack.
The Garuda team's Big Damn Heroes moment in chapter 13. Heralded by this quote:

Talisman: We bring the fires of liberation.

There's one subtle awesome moment for Derpy and Medley in chapter 14. Using a broken piece of turret, Medley throws it at a griffon as a distraction before Derpy dive-attacks him and pushes the enemy toward Medley for a Shoryuken-like uppercut to the beak.
As reported by Flare Star in chapter 15, Blueberry fought against four (!) griffins all by herself and even managed to defeat one before being violently killed. It was a Dying Moment of Awesome for her.
The whole chapter 17 can be seen as this for the Equestrians. Not only Canterlot is liberated, the ponies in other cities decide to lead their own counter-strikes, driving the invaders away.
- There is also Fluttershy fighting against Night Raven. What seemed as a cruel No-Holds-Barred Beatdown at first, with Fluttershy being the victim, she managed to turn the tables after Night Raven revealed to her how much of a Blood Knight he is.
