A Series of Shots is similar to a montage, but takes place in one location during one piece of time. The ship settles on the Washington Monument. Humans are rounded up into Candlestick Park as more ships land in the parking area. An African tribal leader chats with one of the aliens. Police swarm the Federal Building.
SWAT teams aim their guns.
The other lines are Action elements. Whether you add the extra description is up to you. If you write the Montage or Series of Shots well, it's obvious when they end, so I would avoid the ending indicators.
