Aerial Assault
This had better work. Sly won't stand a chance making it through this train unless I neutralize the aerial defenses. Good thing I outfitted the RC chopper with a new cannon.

"Aerial Assault" is a job for Bentley in "He Who Tames the Iron Horse" of Sly 2: Band of Thieves. The goal was to clear out the aerial defenses protecting Bison's second iron horse train.
Bentley jumped on board the second Iron Horse train and deployed his RC chopper so that he could destroy the defenses. With the new cannon he installed, he was able to destroy head-on enemy targets, while still being able to bomb targets below, such as guards and missile launchers.
Once these fortifications were wiped out, Bentley declared it safe for Sly to hop aboard the locomotive and steal the second Clockwerk lung.
