These pages are from Chapter 5 of "Taiwan Report," the 1973 publication that was mailed to incoming personnel. Click on any of the images for a larger version.
This chapter discusses the Status of Forces Agreement (SOFA), which is an agreement between a country and a foreign nation stationing military forces in that country. Most nations that have military personnel stationed in other countries have these agreements.
Also discussed in this chapter are customs rules and identification requirements for military personnel who were stationed in Taiwan.
I just remembered that my wallet seemed pretty thick in those days. With all of those identification cards and maybe a couple of hundred $NT, it's no wonder!
