It is pretty challenging with the forces presented, but can be done. The 4f,g,h scenarios cover convoy escort. In 4f, the convoy is escorted by a MP Company armed with machine guns and grenade launchers. In 4g, the convoy is escorted by an armored MP Company in a LAV, armed with light machine guns. In 4h, the convoy is escorted by a medium infantry company.
Designer notes for the three scenarios above.
Trackless Variant - No engineer support. Other than that, follow the in game documentation. This is the dug in version. Two minefields are already laid. Place in the TF Gallagher folder.
