There is a basic set of targets, as well as several long-range ones that extend over a distance of up to 350 meters.
There is also a killhouse mini-game with randomized target locations.
There are 26 possible targets in the game, of which only 13 will actually stand. Sometimes it crashes for unknown reasons, and only 12 will work, if that happens, just log out and re-enter the card.

Necessary modifications:

[TABS] Vehicles Framework
Installation Instructions:

Install the file.
Unzip the archive to your \User\Documents\Teardown\mods disk or to the mods folder in the root folder of the game.
"If there is no mods folder, create one."
Enjoy.
