 Concurrently, subordinate units General Support Detachment and Direct Support Detachment were constituted and organized (sometimes alternately known and later officially re-designated respectively as Alpha Company and Bravo Company).Direct Support was doctrinally charged with tasks now associated with civil affairs generalist operations, while General Support contained specialized teams for legal, medical, and education support of host nation governments.The 490th provided a detachment of 23 soldiers under the flag of the 321st Civil Affairs Brigade in December 1998 to support Operation Joint Guard in Bosnia-Herzegovina.
