NATO defines indirect fire as Fire delivered at a target which cannot be seen by the aimer.. The implication is that azimuth and/or elevation 'aiming' is done using instrumental methods. Hence indirect fire means applying 'firing data' to azimuth and elevation sights and laying these sights. Indirect fire can be used when the target is visible from the firing position. However, it is mostly used when the target is at longer range and invisible to the firer due to the terrain. Longer range uses a higher trajectory and in theory maximum range is achieved with an elevation angle of 45 degrees.
