Analyze the ground, your approach avenues and the opposing side LOS of them, together with planned area fire by both direct (your units, especially vehicles) and indirect fire support and use lots of smoke when you maneuver. Remember that the javelin operator still needs a direct line of sight in order to acquire your IFV\APC, which is kind of a drawback. I know that CMSF has the spike MR and that one is capable of hitting targets while the launcher and the crew are behind cover themselves, using the optical sensor on the missile as a manner of semi-loitering munition... But I'm pretty sure the game does not simulate that capability
