      USFS and BLM consolidated some of their nationwide freqs and besides 
being used for large fires are also used for special details, law 
enforcement tacticals, and even military exercises in national forests or 
BLM land. Most common are:
168.700  CMD-1
168.100  CMD-2 (used here by military until they switched to 168.375 
digital)
168.075  CMD-3
166.6125 CMD-4
167.100  CMD-5
168.475  CMD-6
168.050 TAC-1
168.200 TAC-2
168.600 TAC-3
173.9125 TAC-4
173.9625 TAC-5
173.9875 TAC-6
     These are sometimes referred to as "NIFC TAC _".
   With 173.9875 being NIFC TAC-6 it's probably a work detail, or even an LE 
op. USFS seems to be switching most Western (and some Eastern) forest LE 
nets from the old 166.125 to 168.025 as the repeater output. Input seems to 
vary. Here it's 164.625 (Cleveland NF). BLM LE repeater is now digital on 
166.750 R, input I believe is 168.300.
   168.325 is the input to USFS "TRAVEL NET" on 169.125, which allows units 
from different forests to communicate at and enroute to major incidents. 
169.125 can be used direct, and each Forest has a different PL (or PL's) for 
various mountan tops & sites. Other FS/BLM tacs on:
169.350 (BLM- digital heard)
166.2875 BLM
167.000 BLM
169.7625 USFS
166.9375 BLM

    I also heard a BLM LE UHF link repeater on 417.575 in the CAL DESERT 
district, called "discrete",
not sure which freq it was repeating. Maybe someone in San Berdoo or 
Palmdale knows...
  I've also heard 168.250 and 168.275 used as tacs on large fires, I'm 
pretty sure they're BLM tacs.
