This weapon is a recon rifle like the SCAR. This means hand grenades instead of launched grenades (of which you carry three more and can fire further). Once you destroy the missile launchers (the Armory objective), the Spetsnaz (Russian Special Forces) who attack you in their distinctive blue woodland camouflage will have these weapons. Grab one temporarily and add it to your collection.
The five gold bars in this mission are hidden at the following locations.
This weapon is difficult to get, if only because you will likely not be here if you ignore exploration. The weapon is at the beginning of the tank ride, in the first house on your right when you are ready to mount up. Because you will trigger the tanks to move if you go too far, you may want to finish the tank ride, then come back exploring. The large white X-mark will clue you in on which house in the valley houses the M249. It is useful to have when protecting the M1 Abrams in the town square. Consider getting this weapon before re-grouping at the red smoke after destroying the Zavrograd communications array.
This could be either the SCAR-L or the SCAR-H (both can be silenced, they just different caliber ammunition). You will use hand grenades with this weapon. The west side of the map has a broken bridge. Check the house just across for the weapon. Haggard will mention that silencers are for girls -- or for counter-terror units.
