That sounds like my Civil Affairs unit -- they've had 4-5 mobilizations in the last few years.
However, CA units are very small and highly specialized, with an unusual mission. It would be a mistake to generalize CA deployments to other parts of the reserves. Other units have much different experiences than CA.
With the emaciation of the active duty military under the Klintoon administration, however, the role of the Reserves and Guard has changed forever. We were mobilized in 2002 for Iraq and we are back in the rotation for 2006. While we were away, our BN had about 100 soldiers join and they are on trainup for Afghanistan as we speak.
