A heavy-duty Warden truck used to mobilize troops and supplies.
— In-game description
The Dunne Transport is the standard WardenTruck designed to be an all-purpose logistics vehicle, capable of moving cargo, equipment, and personnel to various locations. It can towField Weapons and Trailers.
The Dunne Transport, like all trucks, are a valuable part of Foxhole's logistical loop in terms of gathering resources and materials, transporting equipment, and delivering/storing them. As such, it is important to have them stored in either a Seaport or a Storage Depot and not lying around in order for partisans to steal them. If you do not plan on storing it there, then make sure it is behind defenses with AI, as parking them in front will block their line of sight, making them unable to shoot targets.
Trucks are the only way to get a majority of Foxhole's equipment to the frontline, which comes in the form of crates. As such, they are a vital part of getting large amounts of equipment to a base in a quick and timely manner. They are also pretty fragile, and can quickly be disabled by any weaponry in a few shots. As such, it is very important that there is Map Intelligence covering the roads so any partisans can be preemptively spotted and dealt with by frontline forces.
In terms of what drivers need to carry on them when doing this, they should at the very least carry a rifle and two clips of ammo. This is to defend yourself from partisans and to increase your chances of surviving the encounter. While it is not necessary, you can also equip a Gas Mask and two Filters to protect yourself from Gas Grenades.
