I want to pull the trigger to some sort of rocket launcher.  An RPG is probably the most realistic weapon, but maybe the grenade launcher attatchment to an assault rifle would be doable.  **Update.  Apparently you can blow up a cow with an RPG in Cambodia for $300.  I might opt for a junk car or something non living, but cool to know. http://www.traveldudes.org/travel-tips/shooting-bazooka-or-rocket-propelled-grenade-launcher-cambodia/28242
