PROCESSING PLANT

Processing plants are built from light concrete and sheet metal.  A processing plant is used for producing various kinds of chemical substance including nerve gas and solid and liquid rocket fuels.  They are also used for refining uranium ore.  All nerve gas is binary and therefore processing plants can be destroyed at will as leakage of their contents will not contaminate the atmosphere.  Although they are soft targets a substantial amount of shell or machine-gun fire is required to destroy them.
