2.2.2.2 SECRET PASSAGE
A SECRET PASSAGE is a rectangular lane in front of each HUMAN PLAYER STATION. As introduced
in Section 2.1 Zones & Markings, each ALLIANCE has a SECRET PASSAGE; an infinitely tall, 4 ft.
5-1/2 in. wide, 23 ft. 11-1/2 in. deep volume defined by BERMS, the GUARDRAIL and the CASTLE
WALL.
The SECRET PASSAGE includes the BERMS, but does not include the GUARDRAIL or CASTLE
WALL. BERMS the steel barrier, 1 in. tall and 3 in. wide that defines the border of the SECRET
PASSAGE.

Emphasis mine.

If I understand BERMS correctly, they are not verbs.
