How does Pynchon address the theme of war and technological advances in the novel, Gravity’s Rainbow?

Gravity's Rainbow examines themes of war and technological advances from the beginning of World War II through the Vietnam War. Pynchon is concerned about the enormous and complex technologies for destroying human life that have proliferated since World War II. His novel seems to point out that late-twentieth-century mechanisms of destruction threaten not just life but identity and selfhood because they alienate people from their uniqueness and their concepts of who they are. Nearly every character in the novel is drawn from his/her true life and identity (Roger from Jessica, Brigadier Pudding from his sexual fulfillment, Slothrop from his literal identity and his home) because of war and technology. Pynchon may be suggesting that the effects of war and conflict are disastrous, violent, and far-reaching due to late-twentieth century technological advances.
