I did notice that the FFAR (Weapon 175) and HVAR (Weapon 176) were identical in OOB12. The FFAR is more akin to the British RP-3.
Also, at
Designtion Systems.Net it says that the HVAR's range was 3 miles which is consistent with the 96 range. Andreas Parsch's research is very reliable. The FFAR's range should be reduced though, and its stats should not be identical to that of the HVAR.
