Attack on Titan season 3 episode 14 Thunder Spears
Reiner, as the Armored Titan, initially begins climbing up the wall towards the Survey Corps when the Beast Titan gives a signal and the 2-3 meter Titans within Wall Maria rush towards the wall, targeting the horses to cut of the escape route of the Survey Corps. Three squads are sent to protect the horses, while the Levi and Hange squads prepare to tackle the Armored Titan utilizing Thunder Spears. Erwin initially keeps Levi and Armin back, to target the Beast Titan. Meanwhile, the Armored Titan reaches the top of the wall and encounters Erwin waiting for it, but suddenly Eren transforms into his Titan form and flees. The Armored Titan takes the bait, abandoning its target of the horses, and chases Eren. They engage in a battle of force and wits as each tries to gain the upper hand, but Eren's training of hardening his hands pays off as he temporarily weakens the Armored Titan. Hange and her squad then attack it with Thunder Spears, aiming for the nape of the neck. Their initial attack weakens the Titan, so they follow up with a barrage of the spears in an attempt to finally destroy the Armored Titan along with Reiner.
