Also, continuing on a Memorial Day theme, something that the Internet allows you to do is to get access to information and history that you couldn't get very easily. For instance, one of the things I've enjoyed and been awe-struck by are the citations for Medal of Honor winners, which are available here. Here is one from 101st Airborne in Vietnam:
FITZMAURICE, MICHAEL JOHNRank and organization: Specialist Fourth Class, U.S. Army, Troop D, 2d Squadron, 17th Cavalry, 101st Airborne Division. Place and date: Khe Sanh, Republic of Vietnam, 23 March 1971. Entered service at: Jamestown, N. Dak. Born: 9 March 1950, Jamestown, N. Dak . Citation: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Sp4c. Fitzmaurice, 3d Platoon, Troop D, distinguished himself at Khe Sanh. Sp4c. Fitzmaurice and 3 fellow soldiers were occupying a bunker when a company of North Vietnamese sappers infiltrated the area. At the onset of the attack Sp4c. Fitzmaurice observed 3 explosive charges which had been thrown into the bunker by the enemy. Realizing the imminent danger to his comrades, and with complete disregard for his personal safety, he hurled 2 of the charges out of the bunker. He then threw his flak vest and himself over the remaining charge. By this courageous act he absorbed the blast and shielded his fellow-soldiers. Although suffering from serious multiple wounds and partial loss of sight, he charged out of the bunker, and engaged the enemy until his rifle was damaged by the blast of an enemy hand grenade. While in search of another weapon, Sp4c. Fitzmaurice encountered and overcame an enemy sapper in hand-to-hand combat. Having obtained another weapon, he returned to his original fighting position and inflicted additional casualties on the attacking enemy. Although seriously wounded, Sp4c. Fitzmaurice refused to be medically evacuated, preferring to remain at his post. Sp4c. Fitzmaurice's extraordinary heroism in action at the risk of his life contributed significantly to the successful defense of the position and resulted in saving the lives of a number of his fellow soldiers. These acts of heroism go above and beyond the call of duty, are in keeping with the highest traditions of the military service, and reflect great credit on Sp4c. Fitzmaurice and the U.S. Army.
