List of Infantry Uniforms

The following is a list of different combat suits/armor and other various uniforms used by various personel of the United Nations Space Command Defense Force. Note that the following is exclusive to the Infinity Universe.

M671 Infantry Combat Suit
The first of the 26th century infantry suits, the M669 was used during the latter majority of the Insurrection and almost a decade into the Human-Covenant War. This reason the then obsolete armor was used for so long was because a number of colonies didn't have the time or the necessity to receive new equipment. It is fairly well-designed with for its time, utilizing intricate arrangements and sizes of armor plates, though they were not as efficent as their successors.

M673 Infantry Combat Suit
One of the more popular designs of the series. This design was first used by soldiers within the fleet commanded by Admiral Preston Cole during the Second Battle of Harvest. Afterward, all soldiers assaulting the Covenant near Harvest were issued the M673, including those aboard the UNSC Spirit of Fire, Pillar of Autumn, Belfast, Texas, and others. The suit featured a system that analyzed the wearer's heart rate and abnormalites could be automatically reported to a nearby medic, though the machine necessary for this program weighed over twenty pounds and was often deemed unnecessary. The M673 is also known as the first suit to have a two way radio installed in all models along with the majority of suits having a built in video recorder.

M674 Infantry Combat Suit
A prototype tested exclusively by the Office of Naval Intelligence. It was literally a slightly improved M673 with integrated Covenant infantry equipment taken from the battlefields of the First Battle of Harvest. It was not at all meant to be used in combat but was only an experiment to see what the technology was capable. The test failed and the concept was temporarily abandoned.
