The Fortress Infiltration

"'We suffered a deep blow from the Empire recently. As you know, Darth Vader cut down countless of our men by his own hand. We cannot let this stand. If we do not retaliate, then we will be seen as weak, not to mention, our fallen comrades deserve to be avenged. They came this far over the course of this past year, fighting back against tyranny and repression, and we've suffered losses after losses and defeats after defeats. What few victories we have won have been incredibly hard-fought. The capturing of Kamino was a step in the right direction, but we are hardly ready to use any of our new clone troopers. So in the mean time we are going to make the Empire feel the pain we've felt. for every brother that we have lost, we will chop down two of those Stormtrooper scum. We will not rest until they stop lording over us. The Stormtrooper army thinks themselves kings, and their hiearchy thinks themselves gods, well I, for oone, don't buy any of it, and after all, what are gods to non-believers? There's no church in the wild, and we are the forest.' - Rico"Flak reports the massacre on and loss of the planet Ryloth to Rico. Rico admits that they knew something like this would happen eventually, and is glad that they were able to get roughly 5 million men off the planet. Instead of ordering a counter-attack, Rico decides to stop acting so predictably in this war, and orders Flak to collect 20 of his best men and some captured Imperial armor.

Rico later addresses the special task force of clones in Nova Trooper armor, lead by Flak in Scout Trooper Armor. After a speech, he sends the unit to the Imperial base on the volanic planet of Shola, while bringing his own invasion force.

Battle Results
The Volcanic Base is heavily guarded, bot in terms of Magma Troopers, and turrets. Rico's orane-armored invasion force will attack from multiple directions while Flak's infiltration force is already inside. Flak gets found out, and geinto a stand-off with an Imperial Officer in a back room.

Rico's men come under heavy fire right away, with explosions sending volanic rocks into the air, but Rico's men soon take out,and even commandeer several heavy turrets. Rico leads his men forwards towards the base entrance, and take out the base's upper-floor defenses. Flak's force kills the Imperials in the room with them with minimal casualties, and moves through the base, taking out Magma Troopers a few at a time.

Rico's men try to flood the entrance, but the first squads get wiped out, so Rico and Flak coordinate a similtaneous attack on the entrance. Flak's force dwindles, but soon, only a few Magma Troops remain. Rico and his men flood the entrance to take out the remaining Magma Troops guarding the entrance, while Flak takes out a single Magma Trooper they missed. Rico succeeds, winning the planet Shola with moderate causalties.

Trivia

 * Carrying out combat operations while dressed as the enemy is perfidy, a war crime under article 29 of the Geneva Conventions.
 * Other heroic characters in Star Wars canon have committed acts of perfidy without it being noted as a war crime, notably including Anakin Skywalker and Obi-Wan Kenobi (falsely surrendering), Poe Daemeron (pretending to negotiate to get close to a target), and various characters in Star Wars: Rebels (carrying out combat operations dressed as civilians or the enemy) It is possible it it not a war crime in the Star Wars universe.
