Carrier forms are formed from older Combat Forms or from bodies that are unsuitable for combat. Lieutenant McKay theorized that Unggoy and Kig-Yar couldn't become Combat forms and instead directly converted into Carrier forms, though this theory has been disproved.
Combat Forms may be converted when they reach the end of their life span, or become too damaged to fight. Carrier Forms perpetuate the Flood species by acting as incubators for newly created Infection Forms and keeping them safe until they're fully developed. Eventually when a Combat Form has lived long enough, it will also evolve into a carrier, regardless of its status.
Once the Infection Forms are ready, the carrier simply explodes spontaneously, sending the new Infection Forms flying into the air. As soon as the Infection Forms are released, they begin searching for new hosts. It should be noted that Carrier Forms won't wait until full maturation has occurred.
If potential enemy hosts are nearby, it will simply get close to them and explode, sending the Infection Forms flying at the unsuspecting and often injuring or killing enemies. The explosion of a Carrier Form is similar to the explosion of a fragmentation grenade, and deals damage to anything nearby.
The Carrier form has a simple mindset, which is to release the Infection Forms it carries to a suitable host. Other than organic bodily sounds, they cannot speak or make any other sound. Though they can somehow communicate with other Carriers, possibly through a Gravemind or Brain Form, to inform them of a potential sentient being.
Carrier Forms are usually considered slow and of little threat unless they are close to the player. However, one particularly dangerous trait of exploding Carrier Forms is the explosive chain reactions they can cause. A Carrier explosion will cause any other Carrier Forms close enough to explode also. They also cause any nearby explosives or objects to explode. This means a single Carrier can cause a massive explosion through a chain reaction filling much of a small area. This can be used to a soldier's advantage if there are Combat or Infection Forms surrounding the Carrier(s). They are sometimes considered a 'flood grenade'.
Any direct explosion eliminates the threat of the Carrier, as well as any Infection Forms that were incubating inside of it. This means that enough needles from a Needler will kill it, or you can throw a grenade down and kill it.
Carrier Forms are one of the easiest enemies to take down. One shot from any weapon save,the Plasma Pistol will force it to explode. However, there is not a single weapon that can actually blow it up, not even a direct Rocket Launcher. Therefore, this has to be taken into account, strategically. For example, when confronting a large number of Flood, you may wish to destroy the Carrier Forms, which in turn will kill all nearby Flood. First, allow the Combat Forms and other to get reasonably close. Then, use any weapon- preferably one which has ample ammunition- to kill it.
It is not recommended to use sniper rifles against the Flood; it is simply a waste of valuable ammo. In any case, sniper bullets simply pass through Carrier Forms, dealing virtually no damage.
In Halo: CE a good tactic is to hook one with a Plasma grenade and shoot it with a shotgun this will kill the Infection Forms inside. Running over Carrier Forms is a very bad idea. Their explosions will easily flip your vehicle, wasting precious time.
In Halo 2 was to be a variant of the normal flood carrier named Shielded Flood Carriers, they didn't make in the final game but this code is encrypted in the Halo 2 disc so they can be modded in the levels that the Flood appear.
