Chim,
There have been many recent leadership failures (AFPC, AFGSC, Lackland, etc) but there are plenty of examples of good leadership and great leaders. It is too bad you haven't been around any.
Maj Gen Greg Lengyl, Commandant of Cadets. MH-53 pilot brought common sense, warfighter focus and empowered leadership to AFA
Gen Robin Rand AETC. One of the finest, most selfless, professional, tactically savvy leaders in our AF. Led the 332 AEW in Iraq 2006-2007.
Gen Hostage, ACC. Incredible combat leader, one of the best COMACCs.
Maj Gen (sel) Pete Gersten. Transformed RPA lethality at Creech and on ACC staff at Langley
Gen Paul Selva, TRANSCOM. Selfless, honest, intelligent MAF leader.
Brig Gen (sel) Rick Rupp, McConnell Wing Commander. Led by putting Airmen first, awarded O'Malley Award in '13
Maj Gen Jeff Harrigian, CENTCOM DJ3, aggressive, creative Airman leading in a very Army centric command.
Lt Gen John Hesterman, AFCENT/CFACC. Ready and willing to use airpower to bring any nation to their knees. A great leader doing a tremendous job in CC.
CMSgt Colon-Lopez, AFCENT/CCC, combat hardened PJ, no-nonsense enlisted leader. Would make a great CMSAF.
