Continuing the line of "missile built at ungodly hours on no sleep"
This is the R-5
It's like an R-2, but big
[list]
[*] 3.2km radar range
[*] 4-5km effective launch range
[*] Smokeless motor
[*] Flies very stably, capable of hitting small targets
[*] Maneuverable enough for most thing you come across
[/list]
Requires no extra setup or vehicle side infrastructure
Just mount it to a hardpoint, point it at something and fire
