question:
Question: Where was the division based that was able to dig in for a defense of Bastogne? Passage:The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier. When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting. The Division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas. Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city. After a rest period in January 1945, the Division prepared to drive across the Roer River. The offensive was launched on 28 February 1945 and the 9th crossed the Roer to Rheinbach, sending patrols into Remagen. On 7 March 1945, elements of the 9th Armored found that the Ludendorff Bridge was still standing. When German demolition charges failed to bring the bridge down, they crossed it, disarming and removing the remaining charges, which could have exploded at any time. The Division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA. The Division drove on to Frankfurt and then turned to assist in the closing of the Ruhr Pocket. In April it continued east, encircling Leipzig and securing a line along the Mulde River. The Division was shifting south to Czechoslovakia when the war in Europe ended on 9 May 1945. All units of CCB/9 AIB of the 9th Armored Division were awarded the Presidential Unit Citation for their actions in taking and defending the Ludendorff Bridge during the Battle of Remagen in World War II.

question:
Question: Which military branch that Penson may have served for has more active members? Passage:Penson's professional career began in April 1954 after he had had a successful three-year skein as a pitcher while he served in the military. Penson won 50 games pitching for his base team, although sources disagree about the branch in which he served, reported as the United States Air Force and the U.S. Army. Penson made the Phillies out of training camp in 1954 as a member of the team's early-season, 28-man roster. His five games pitched included three starts, and he split two decisions. His lone MLB win came in his first start, on Sunday, May 16, 1954. in the second game of a doubleheader at Connie Mack Stadium. He went six innings against the St. Louis Cardinals, and allowed four hits, four bases on balls, and one earned run. But he was forced to leave the game leading 63 when the game was suspended because of Pennsylvania blue laws prohibiting sporting events on Sunday evenings. The game resumed on Monday, May 17, and Philadelphia went on to win, 84; veteran Murry Dickson nailed down the save with three innings of one-run relief.
