If you get KeyGetys addon pack then it is possible to create bushes without using the camCreate command and if you want to simulalte a cruise missile you could just camCreate a hellfire missile over a unit or whatever and then the hellfire will fall and detonate over the unit
use my little script that I cooked up
;Just an Explosion Script Used to destroy any object with multiple or one HEAT120 Shell
;[explosion,"HEAT120"] exec "explosion.sqs"
;Pass the object through the script
_unit = _this select 0
_shelltype = _this select 1
;camCreate the Bomb over the position of the car
_bomb = _shelltype camCreate (getpos _unit)
~0.01
;Check if unit is still alive, if so then blow it up again.
?(alive _unit) goto "start"
;Exit the Script
exit
you must call the script through an init field,script,etc using the following sintax
[_unit,"_shelltype"] exec "explosion.sqs"
if you wanted to use a hellfire you would use
[dude,"hellfire"]exec "explosion.sqs"
_unit being the name of the object for the missile to target and _shelltype the type of shell to use to destroy the object
