Koukaku Kidoutai: Stand Alone Complex, Senkou no Night Raid Recommendations
Both have political backgrounds which are heavily discussed. Both have secret government organizations with adult characters who have special set of skills and worked as a team. Both have awesome and jazzy music. Difference is that GITS sets in the alternate post-WIII while SnNR sets in pre-WWII.
By all means, this series is basically Chinese super-powered 1930's Ghost in the Shell. Most of the enjoyment comes from the intricate infiltration/action sequences, mature characters, political story and great music.
