Machete:  Blade used for cutting vegetation to clear a path, campsite, etc.

Mantlet, Moveable:  A wooden wall, with wheels for mobility, and a slit for archery.  It is typically 1.8 meters wide, 2.4 meters high, and 10 centimeters thick.  The mantlet is slanted backward at a slight angle.  The face is often covered with green hides to reduce the risk of fire.  Mantlets can be constructed at the site of a siege from materials available.  The values below are for pre-fabricated mantlets.  Two men can push the mantlet forward at a rate of 2 meters per turn.

Map, Electronic:  The "map box" is a compact (25 × 25 × 1 cm, which expands to 100 × 100 × 1 cm when opened) display system for computerized maps of a world.  Scale may be adjusted.  Most inhabited planets have mapclips (diskettes until TL 13, holocrystals at higher levels) available for §150. When not available, two orbital sweeps of the world are required to obtain the necessary photographs to construct a map chip.  Blank map chips are available for §30.
