The existence of these private communities is a testament to the longevity of Arma 3. While the public servers may be transient, these private units often sustain themselves for years or even decades, with a constant churn of members and a core group of veteran developers who steward the unit's private assets.

Rumors persist of a terrain pack containing high-resolution satellite data of sensitive military bases (fort Irwin, Nellis Range, etc.) generated via photogrammetry.
