As I wrote yesterday, the answer to enemy convoys is Napalm.
Rockets, bombs and strafing are nice, but not necessary destructive enough if you don’t have enough air assets to strike the whole target area effectively.
Napalm covers everything in its path, and its path can be a long (and wide one), depending on how the canisters are dropped (two, side by side, simultaneously), or single drop in a line.
I suspect that they French are trying to fight this war on the cheap, like some other power I know. That is NOT the way to fight in the desert. You hit the enemy with everything you can bring onto them. Again, Napalm is the weapon of choice for mass destruction of enemy forces.
Also, it is a weapon that creates massive fear in the enemy. It was, according to my combat friends, the most feared American weapon in Vietnam.
Time for the French to take the croissants off the table and put on some iron gauntlets.
Drones.
