Robert Waarvik, 435th Contingency Response Group vice commander, following a three-day tour of the CRG, Dec. 6, 2012, at Ramstein Air Base, Germany. Five members of the Nigerian air force quick response force visited CRG to gain a better understanding of their construct, capabilities, and employment.
