+-- WEAPON: Track Shell
+-- 
+-- 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".
+---
+
+-- Some message on screen.
