Can deployed troops be given directions?

[Rabies]

Upon inserting troops via helicopter, they advance only so far towards the enemy and eventually stop at a specific location marked by a flag. Is there anyway you can move that flag in multiplayer so they continue to move and engage the enemy?

Infantries and ground units in general in DCS are still not very reliable. The Combined Arms module is being or will be upgraded as well as ground units. Currently, assigning waypoints can be bugged sometimes, especially for infantries. Make sure their status is showing "green" and not "red" before assigning waypoints. That works sometimes.
