-Objects are independent of the cell grid structure. They are placed on the map using their own dimensional space transform.

 Unlike cell indexes however, each identical pine tree is listed separately, rather than simply have a table. There's no particular reason why a table (and indexes) weren't used to conserve space, but done, it wasn't. Unlike cell indexes however, each identical pine tree is listed separately, rather than simply have a table.

-For the purposes of game play, and no other reason, each, identical pine tree has a unique 'ID' number. (as does every other object). A soldier is told to goto THAT pine tree (as opposed to any other). The IDvalue, while guaranteed to be unique, is highly arbitrary. Any alterations / additions / deletions to the map and it's objects will result in different numbers for some / most / all of the objects. This represents no problem with game commands using NearestObject() style functions that return the ID of relevance, but, missions relying on a specific building ID (eg) will mostly fail if the 'island' is revised. This has particular relevance to porting OFP islands into Arma.+For the purposes of game play, and no other reason, each, identical pine tree has a unique 'ID' number. (as does every other object).
