Answer

Would have to see the movie to be sure of what they mean.

Answer

The flanks are the areas to the sides. He's not flanking, and there are probably no armies there, but possibly some enemies. The use of 'tie in' is confusing to me, and it's not clear what they meant.

Answer

'flanks' are the areas to the right and left sides of him. It's a military term, or at least the meaning is here. For instance, if you were marching in an army column, your left flank is the area to the left. Imagine a rectangle piece of land to your left - that is your flank.

In your text I think  he wants the dozers to secure/clear these roughly rectangular areas of land to his left and right.

Answer

Greg/thanks. do you think 'flanks' means 'armies' or 'his flanking operation'?

Answer

Not sure. My guess would be he wants his flanks secured by having the dozers come and clear away debris/shelters where the enemy may be.
