Even when your units are sufficiently leveled, the Marmota requires several direct hits to destroy. Using Jann Walker a certain way, however, makes things much easier. After blowing a hole in the Marmota, reach its upper deck with Jann and Largo. Activate the Awaken Potential and Demolition Boost Orders for Jann. The Awaken Potential technique increases the likelihood of a characters' special abilities to activate. This gives Jann a 40% boost in attack damage if he's standing close enough to Largo, a 40% boost in accuracy, and a 90% boost against armored enemies. It also gives him a better chance of randomly inflicting double the amount of damage. It also gives him the Extra Shot ability to randomly acquire more ammunition without sacrificing another turn to reload. When fully stacked, these Orders and Potentials give Jann enough attack power and accuracy to take down the Marmota in a single turn.

Enter a skirmish. Use "Caution", "Evasion Boost", and "Defense Boost" on Alicia. You will lose health very slowly when taking fire. It will take two turns to reach the end. End your turn while Alicia is safe somewhere along the way to reset her AP. Note: If you have Largo and Rosie in your squad you will get a free CP.
