How does James A. Michener use imagery in Tales of the South Pacific?

Imagery:

"Out came a rear admiral with the zipper of his pants caught in his underwear. 'Goddamned things. I never wanted to buy them anyway. Sold me a bill of goods.'" p. 11, The South Pacific

"Without waiting a moment he literally rushed into the formation, sank one and hung onto another, dodging shells, until his mates could close in for the kill." p. 74, The Cave

"Then he grasped the tusks firmly and with a harsh, wrenching motion, tore them loose from their long tomb of misery. One he gave to Fry, one to the chaplain." P. 262, A Boar's Tooth
