Use a text editor to edit the files in the directory: 
"/Program Files/America's Army/System/descriptions".  
For example, change:
"Name: Trijicon ACOG Reflex Sight Function: " to "Name: Trijicon ACOP 
IS TRYING TO Function: " then attempt to save it. A number of errors will appear.
Click "Okay", then right-click the file you are trying to overwrite (for example, 
"MOD_Acog_Reflex", and go to "Properties". You will see a box on the bottom labeled
"Read-Only File". Un-check that box, and you will be able to save over it. 
Then go in-game, go to modifications, select what you modified, and read it to 
see your modification.
