..it's in the link I gave you....the first bullet point

Support expeditions involve sending a fleet into an expedition to provide additional bombardment during the opening stages of Combat. There are two types of support expeditions, normal support and boss support: Some important points about support expeditions are:
 * Expedition 33 (15 minutes) is a normal support expedition, only works for pre-boss nodes.
 * Expedition 34 (30 minutes) is a boss support expedition, only works for the boss node.
 * Events come with their exclusive support expeditions (e.g. expeditions 133 and 134 for normal and boss support, respectively) that can only be used throughout the event.
