During times of relative peace, some OUs have most or all of their weapons systems removed, and are known as (demilitarised) Rapid Offensive Units General Offensive Units? Limited Offensive Units? ((d)LOUs).
For various reasons, some allegedly demilitarised (d)OUs actually still retain most or all of their armament; this is usually due to some faction wishing to covertly maintain a fully armed warship presence, such as Special Circumstances or an over-cautious Hub Mind.
(d)OUs maintain the same ship classes as they did when they were active service OUs.
