Health kit

The Health Pack is a first aid kit containing the standard combat wound treatment, which is used by all UNSC combat personnel, ranging from Marines to even Spartans. Each Health Pack contains an amount of biofoam, a stitch kit, polypseudomorphine, self-adhering antiseptic battle dressings, and other useful field dressing components.

Health Packs are standard requirements aboard many UNSC ships for medical events. Health packs are often seen on corridor walls at regular intervals. There are also two health packs located in a Pelican. Both of them are on each side of the door to the cockpit. They seem to be more rectangular in shape than regular health packs and are inaccessible to the player.

Gameplay
The Health Packs are present in Halo: Combat Evolved, Halo 3: ODST and Halo: Reach only. In Halo: Combat Evolved, the Health Pack would fill the player's health, but would have no effect on their shields. In Halo 2 and Halo 3, health regenerates with an integrated biofoam dispenser within the new MJOLNIR Mk VI. In Halo 3: ODST, the health packs are dispensed from Optican Medical Kiosks and they use a privately-manufactured healing agent known as MediGel. In Halo: Reach, the Health Packs are nearly identical to those seen in Halo: Combat Evolved, with a noticeable difference being the change of the symbol from a red cross to a red uppercase letter "H".

Trivia

 * When you use a health pack for the first time in Halo: Reach you are awarded the Doctor, Doctor achievement. It only gives 5G.
 * When a Health Pack is picked up, the player will become momentarily blinded by a white flash. However, this goes away instantly if passing through a teleporter.
 * The reason why the red cross was removed from Health Packs is that the International Red Cross objects to the use of red cross symbols in inappropriate contexts. Around 2006, after the release of Halo: Combat Evolved, the Red Cross took the position that use of red cross symbols in video game "health kits" is inappropriate, and game developers ceased using them.
