Do you mind sharing how you use r73. My r73 seem can only hit targets when my enemies are not aware. also my r73 seems not tracking targets sometimes
Locking enemies with radar/irst helps quite a bit against pre-flaring. If you have the chance make sure to get within 1.5km before firing one. Sub-kilometer shots are almost guaranteed kills. They sometimes spin out and lose track or some weird stuff happens but otherwise they can be somewhat reliable at closer ranges from side/rear aspect.
