-- # Description:
--
-- An SPH M109 Paladin is doing target practice and tasks to fire one life shell at the old runway at Kobuleti.
--
-- We monitor the SHOT event and track the shell until it impacts.
--
-- The impact point is marked with red smoke and a mark on the F10 map is shown.
--
-- We also use a callback function "WeaponImpact", which is called when the shell has impacted
-- and check if the shell fell into a zone "X".
--
-- NOTE: It takes some time until the paladin will fire. Be patient or use time acceleration.

-- Some message on screen.
local text = "Starting Weapon Test mission"
MESSAGE:New( text, 120 ):ToLog():ToAll()

-- Create an event handler that monitors the SHOT event.
local handler = EVENTHANDLER:New()

--- Function called when a tracked weapon impacts.

  if impactcoord then

    -- Check if impact was inside the target zone.

    if inzone then
