求翻译：On the battlefield, Air Force vascular surgeons pioneered new methods of hemorrhage control and blood vessel reconstruction based on years of combat casualty experience at the Air Force Theater Hospitals in Iraq and Afghanistan. The new techniques include less invasive endovascular methods to control and treat vascular injury as well as refinement of the use of temporary shunts. Their progress has saved limbs and lives and has set new standards, not only for military surgeons, but also for civilian trauma.是什么意思？
