This is true. If your have a nice woodlot with a good mix of trails and dense foilage, you don't really need any FIBUA materials.
The only thing I would really suggest is building two or three main "bases", and maybe one little area with man made cover. Leave the rest natural so players can practice small scale manouvers and tactics.
