Seward Square Artillery
Seward Square Artillery is a holodisk in Fallout 3. It can be found on a small skybridge east of the Capitol Building (accessible via the Office of Urban Planning office building) in Seward Square, next to a switch.
Artillery Order #562
Talon Company Support Team Alpha
Location: Seward Square
Take position on the skybridge near Seward Square and protect the squad's right flank. Bring plenty of ammo because you're going to be there for awhile. A small team has been dispatched to secure the Capitol Building's south wing. We suspect minor resistance in that sector, but if need arises, we've locked in some artillery coordinates. Call in the strikes by using the switch we've provided for you.
