Operation: Toy Story
From Disney's Hollywood Studios Wiki
Operation: Toy Story is a retired Mini-Parade/Meet and Greet that took place on New York Street, now known as Streets of America, that started June 9th, 1997. The Green Army Men's Van and a wagon filled with a mountain of toys stormed down New York Street bringing Woody, Buzz and their friends out to sign autographs and pose for pictures. Sarge and his troop of Green Army Men call the shots during the 20 minute session in which guests also can meet Bo Peep, Rocky Gibraltar and Troll.
This was Disney's equivalent for having the Toy Story characters when Toy Story - The Parade was replaced.
