Spartan, with Val Kilmer, is about high profile human traffic and the governments special teams to address problems slike that. Many of the operatives on these teams are highly trained survivors of war, in this instance Gulf War One. Moving into the private sector, these highly trained and valuable assets find gainful employment among government agencies in need of that type of thing.
In this movie there is direct graphic reference to some of the skin cancers that were picked up by the Gulf War One troops, and the psychology of being infected with these incurable and even infectious by products of illegal biotechnological warfare. There is more than one statement about staying as far away from the desert as you can.
Most of the gulf war one medical records referring to this were destroyed when the Murrah Building blew up in Oklahoma City, one year after the Waco incident.
