Objectives

Offer: Hey! Attention! Oh, I'm sorry... If you're not busy and all, can I ask you for help? Let me introduce myself. I am Master Sergeant Fox from the Alpha platoon. We got on the aeroboat to get here to complete an important mission when there was an accident on the plane. We all had to parachute our way down.
The problem is, I can't find any of my men that I parachuted with around here. We were supposed to gather up here, but days have passed and I still haven't heard a word from my men. Because of that, can you find them for me? They are all over Ossyria, scattered everywhere. I'm not asking you to do this for free, of course. I'll reward you for your hard work.
In progress: Ohhh... looks like you haven't met all three of my men. Harder than you thought...right? Please meet them in the order of ranks from the highest. I'm sure you can figure that out by yourself.
Completion: Zzz... zzz... huh?! Wha— I'm awake! I was NOT sleeping!...Oh. You're not the Master Sergeant. Phew.
Wait, Master Sergeant Fox sent you? He made it to the rendezvous point?! That's a relief... After the aeroboat went down, I landed here at Orbis and haven't been able to find a single member of the platoon since. So the old man's alive and barking orders as usual, huh.
