How can I change the field names (not the alias) in ArcGIS 10.2? 

I already found this page on ArcGIS support: "[Renaming shapefile fields (Defense Mapping)][1]" but there is is not "**Defense Mapping**" on Customized Mode Categories In my ArcCatalog!

Can you please let me know how I can have access to Defense Mapping or how I can change the field names?
