Scouts Out! Cavalry Ho!
1-Build strong convoys; arm the vehicles, provide escorts, etc so the convoys can fight their way thru.
2-Secure the route; outposts, patrols, etc so the convoys just roll right thru.
3-Go after the bad guys until they are all killed, captured, running away, or have given up the fight.
The last is the best & decisive way, but is also the hardest to achieve. We are doing a combination of all three methods based on the specific route, the enemy, the friendly forces available, etc.
