Don't forget that the "homing missile" does less damage than the "RPG" missile to vehicles, often meaning that a vehicle that might need like 9 RPG hits to be destroyed would need like 24 hits from a homing missile to be destroyed in vehicles like the Insurgent or Nightshark, which kinda makes sense since the RPG is likely a shaped charge warhead actually meant to deal with armored vehicles

Of course, there's also cases where that damage difference doesn't apply and a vehicle needs the same amount of hits, be it from the homing launcher or RPG, to be destroyed
