This is neatly looking device is actually a notepad with a cookbook attached to it! Not only can you take notes (duh!) e.g. during briefing, you can also look up your favourite Marine Gold Star recipes!

CD player

For your amusement, in your pit, during ground Ops (the non-stealthy ones, off course!), whenever you feel like it.

Playing some Metallica when strafing chigs can be really soothing...

Geiger counter

Used to measure radiation. Measures a number of mrad, the unit in which radioactive radiation is measured. Also has a visual indication of the level of radiation, varying from white (tolerable) to red (get out of there !)

Global Position System - GPS

This device allows you to pinpoint your location, provided you are in range of a GPS net. This net consists of at least three satellites orbiting the planet you are at.

Three satellites send out a specific signal. These three signals can be used, through triangualtion, to determine your position. One satellite is added for control. This device receives these signals and, through triangulation, taking into account signal timing, your position can be determined.

Handcuffs

Preferably used on the enemy, to limite his movement. Can also be used in a more intimite ambiance, although this is not recommended. The two square parts are electromagnetically locked and unlocked through the use of an electromagnetic "key"

Fighter pilot helmets

This is a typical assortment of helmets used by pilots of craft like the SA-43 hammerhead. Usually rather colourfull, they are in a way a reflection of the jock's personality. The pilot's callsign is usually painted on the helmet as well.

However, because of all these bright colours, flight helmets are not well suited for ground combat. Below you'll find more info on functional tactical helmets, used on the ground.

This is your typical USMC helmet as worn during ground Ops. The visor can easily be lifted, which allows you to breathe freely. Your name is clearly visible, which is still undesirable from a tactical point of view.

These helmets, typically made out of a composite material containing kevlar, can sustain damage from fragmentation grenades. A bullet, however, when hitting the helmet almost in straight line, will go right through. Bullets hitting at a low angle will ricochet off the helmet.

A helmet is no good if it isn't fitted properly. A well fitted helmet won't hinder your sight and won't "wobble" when walking, running or dodging.

All helmets come with a built-in HF radio and can be closed airtight (rebreather requested!)

This helmet was used during the first assignment of the 58th on Mars. It was to be equipped with a night visor (red lens with crosshair).

Note: not used in the series due to Kristen Cloke being hindered by an eye infection at that time. <homervoice>Damn you, eye infection!</homervoice>

This silly looking gadget is the helmet worn by the Tellus colonists, may they rest in pieces. It should protect the colonist during take-off and landing, and, failing to do that, it's real primary purpose is to act as an oxygen mask. It is equipped with a visor that allows for easier flow of oxygen through a tube, mounted on the bottom of the visor. It is not airtight, hence it should not be used outdoors in an oxygen-poor environment!

It offers little protection against wind, sandstorms, flying debris.
