+-- # Description:
+--
+-- In this demo mission we will show how to use the method IsAlive() on group level.
+-- Two ground forces GROUPS are shooting each other (T-80 vs M2A2).
+--
+-- # Guide:
+--
+-- 1. Run the mission and check the messages.
+-- 2. If a unit is dead the returned value will be nil
+
+-- Create Spawn Groups:
+local GroupBlue = GROUP:FindByName( "Blue" )
+local GroupRed = GROUP:FindByName( "Red" )
+local GroupObserver = GROUP:FindByName( "Observer" )
+
+-- Start a scheduler to test every second if the groups are alive and post a status message.
+local Schedule, ScheduleID = SCHEDULER:New( nil,
+  function( GroupBlue, GroupRed )
+    local IsAliveBlue = GroupBlue:IsAlive()
+    local IsAliveRed = GroupRed:IsAlive()
+
+    GroupObserver:MessageToAll( "IsAliveBlue=" .. tostring(IsAliveBlue) .. " ----- IsAliveRed=" .. tostring(IsAliveRed), 1 )
+  end, { GroupBlue, GroupRed }, 1, 1 
+)
