The 841st Transport Battalion is one of the four battalions of the 597th Transportation Brigade. This formation is in turn subordinate to the Military Surface Deployment and Distribution Command (SDDC), which itself is subordinate to US Army Materiel Command (AMC).
AMC is shown with a strength of 1,830 (Active), 423 (Reserve), and 56,617 (Civilian). Note the relatively small proportion of military personnel to civilians in the very, very large organisation. (My guess is the majority of the military personnel are found at Battalion and Brigade level so for the purposes of a TOE for the 841st, the Civilians can be ignored for the most part).
Although I'm unable to dredge up anything specific to the 841st, or even the 597th Brigade, some information is available for similar Corps level transport units. FM 54-30, Chapter 5 may be of some help

The best I can find relates to the Marines however:
http://www.globalsecurity.org/milita...smc/to/support It's not perfect, and may not even be all that accurate, but should at least get you started. If you need more info, why not contact the unit directly and ask what their TOE was back in the 90's?
