US FM 3-09-12 TACTICS, TECHNIQUES, AND PROCEDURES FOR FIELD ARTILLERY TARGET ACQUISITION

I guess AB might get some hint about artillery operation from this FM.

Chapter 2 discuss about organization & responsibility of CB radar & target acquisition units.
Chapter 4,5,6 discuss about location of radar and other technical aspects such as coverage area.
Appendix E contains technical/operational aspect of AN/TPQ-47 radar.

I didn't read this yet, it seems globalsecurity has limit of articles to read without charge. But I recommend devs to read those articles.

If location of CB radar is recommended to be inside AO, then I guess AB can depict CB radar units in the map. Or, it might be possible to introduce artillery HQ and implement CB radar feature to artillery HQ units.
