Barrel

Barrels were standard storage devices for excavated oil, and were used to transport and temporarily store crude oil before transporting it to a refinery. Due to issues with storage, they were often scattered around the base, and due to the oil's flammability, posed an extreme danger if and when detonated. In, barrels are placed in certain spots (usually with vehicles next to them) as the mission starts you with infantry that are ineffective against vehicles.

In Red Alert 2 and in Red Alert 3 Barrels will still blow up nearby units when attacked.
