Not really recommended, they cost a lot of resources and the maps aren't hard enough to justify using them. The Expedition page has details on how support expeditions work in general, give it a read.

If you're having a lot of trouble at E-1/E-2, you could give them a try and see if they help, make sure to sparkle the flagship though, otherwise they only have ~50% chance to appear.

E-5's final boss kill is the only map I'd recommend using support for, though even that only applies to player that are level ≥105.
