Hawk's cancer a cop out
In order for the rest of the men to get back safely, one of the men had to sacrifice his life.
Fortuntely, Hawk had cancer, so he was the obvious choice...and his death wasn't really that heroic.
Now, if he hadn't had cancer, and was giving up his life solely that the rest of his friends might live, that would have been heroic.
But it's a cliche. Whenever a character in an adventure film has a disease, you just know that later on in the movie, they'll sacrifice themselves for their friends.
