Tom Clancy's Ghost Recon Advanced Warfighter (GRAW) is the third installment in the popular Ghost Recon tactical shooter video game series, published by Ubisoft in 2006. As in previous Ghost Recon games, players command their team of Ghosts while neutralizing hostile forces and completing various mission objectives. These objectives can range from escorting friendly units across the map to rescuing hostages or taking out enemy artillery. Being a tactical shooter, Advanced Warfighter places emphasis on using cover effectively in order to stay alive, together with sound strategic co-ordination to successfully complete mission objectives. A new feature is the Integrated Warfighter System, a system based upon the Future Force Warrior program. Tom Clancy's Ghost Recon Advanced Warfighter 2, the game's direct sequel, was released a year later, in 2007.
