Ammunition plants have two types of traffic - internal and external. The internal traffic is movement of materials between different manufacturing buildings and storage facilities, and is done with Army boxcars and flatcars. External traffic is done with Containers, which normally run in unit trains.
Ammunition destined for US destinations normally move by truck. Ammunition destined for foreign shores are moved via unit COFC trains. There are very few unit ammunition trains, except it time of war.
Smaller ammunition plants use track mobiles to move cars around, medium size plants with have 80 Ton Center cabs, and large plants with have red GPs.
While unit / division designations are borderline off-topic, it should be pointed out that 1 ID will be moved to Fort Riley, KS and 1 AD will be moved to Fort Bliss, TX in the next few years.

Army Forts are more interesting to model, but a lot more work (and more expensive) to do them authentically. Roco and Trident models of US Army equipment are getting harder to find. Boley makes very toyish vehicles, but they don't look very realistic.
Army Forts usually have a pair of GP10 locomotives, although GP40s (Fort Hood, Carson and Leonard Wood) and GG2000s (Fort Lewis, Sierra AD and Fort Irwin) are starting to show up in the Army system.
