The Sea titan (Attack on Titan）

Setting out

"Just before sunset huh? That's smart Armin." He complimented, watching as the scout balloons scattered into the sky. They would scout the area ahead for the rest of the corps.

Him, Eren and Armin had already settled the controversy from earlier and have just decided collectively to forget it had ever happened. 

In the skies at least eight operational balloons were spreading out in formation while the lifts and machinery work tirelessly to transport their horses over the wall.

"It's finally time...." Eren muttered, he looked to his three friends, this is it, he will help them get their home back.

"Hey! Hanji! Marty! Goof luck!" Flegel? Right, Flegel shouted from below them.

"Take it back!"

"Take back wall Maria for us!"

"The future of humanity is in your hands!"

"Captain Levi! Thank you for saving our city!"

"You all come back in one piece, all right?"

"But go and reclaim our territory!"

"Wow, the crowds are really sending us off....has the scouts ever received this type of send off before?" He asked Hanji who was beside him.

"Well they're bound to find out after the commotion we made...and no...I don't think we've ever." Hanji responded, looking happy and excited as well.

"Yes! We'll do it for sure!" Connie Sasha and Jean shouted from a bit further away.

"As far as I'm aware, this is a first." Erwin concluded before raising his fist, smiling genuinely.

"HYAAAAAAAAAAA!" Erwin screamed uncharacteristically, surprising both him and Levi.

"HYAAAAAAAAA!" The crowd cheered back from below.

"The final operation to retake Wall Maria will now commence!" Erwin commanded, brandishing his sword in a truly spectacular fashion.

"HYAAAAAA!" the rest of the soldiers screamed as the last of the horses were carried down.

"ADVANCE!" Erwin ordered. The entire formation spreading out and moving off to ride their own steed into the titan infested wall Maria.

(A few hours later)

He was keeping himself calm, resting on his horse Lyla as Hegemold pulled it along the rein. Currently they were supposed to be near the city now. It's nearly dawn, if they don't arrive in time they could still use the long range scouting formation since the balloons are still in the air. However, they will certainly be delayed by a lot.

The horses need rest as well, so the majority of the legion is just pulling them along slowly.

Most people have collected into their individual groups chatting amongst themselves. A stand out would be Armin and Jean chatting with each other. 

He collected his thoughts as he revised their strategy. There are two gates that needed to be sealed, he would station himself on the outer gate and create a barrier using ice and the nearby river. Ymir would escort Eren and the hero of Trost himself will seal the gates.

If titans appear in the city they would have the veteran scouts deal with it. While the new recruits in the rear would protect them from ambushing titans. He would be the one responsible over them while the scouts engage titans in Shiganshina and make sure they have an escape route.

When the Armoured or Colossal titan appears he would have to stay in position or switch depending on where they appear. His main target would be the beast titan. Since both of their titans fight at range he was perfect for taking down that monkey or at least slowing it down.
