1. Sand Bags
Sand Bags provide heavy cover for Infantry, and allow weapons with bipods to be placed on top of them. To build the sand bags, the engineer must have at least 5 resources for every feet of sandbags. One engineer can construct these.
2. Barbed Wire
Barbed Wire is a mostly impassable obstacle to enemy infantry. It can even cause death if the enemy has low enough health. To build the barbed wire, the engineer must have at least 10 resources for every foot of wire. One engineer can construct these.
3. Tank Trap
Impassable to most vehicles, the tank trap makes most vehicles unable to get to an objective, or blocks off a route. Each tank trap costs 25 resources. 2 Engineers are needed to construct one.
4. Machine Gun Emplacement
The Machine Gun Emplacement is a safe place where Heavy Support classes can set up in. It is protected from most sides, though not against direct fire. Each machine gun emplacement costs 120 resources. Three engineers are needed to construct one.
5. Ammo Dump
The Ammo Dump is basically a large Ammo Box. The Ammo Dump can refill most kinds of Ammunition to their full capacity. However, Ammo Dumps are highly explosive, and can only be built in certain areas. Each Ammo Dump costs 75 resources. Four engineers are needed to construct one.
6. Fuel Depot
The Fuel Depot is the vehicle equivalent of the Ammo Dump, and it refuels any kind of fuel for ground vehicles. It is even more explosive than the ammo dump, though. Like the Ammo Dump, it can only be built in certain areas. Each Fuel Depot costs 85 resources. Four engineers are needed to construct one.
The Triage is a large emplacement that can be placed anywhere. When in the triage, all friendly players will receive healing, and can receive HP Buffs from staying in the triage. Each Triage costs 90 resources. Four engineers are needed to construct one.
