The Armored Personnel Carrier (APC) has been an important component of any military infantry since the latter half of World War I.   Approaching the later stages of the conflict, Allied Forces had employed tanks that could more easily break through enemy lines.  At the same time, though, ground troops following the tanks were inversely more vulnerable to small arms and other artillery.

BASIC APC USE

The fundamental purpose of the Troy Armoring APC, of course, has always been to protect infantry soldiers.  But the amount of protection (armor) provided—as well as additional functions—vary greatly, depending upon the type of vehicle and where the conflict is taking place. For example, some were outfitted with wheels, which served them better on paved streets.  Others had tracks (just like a tank), which gave them improved maneuverability on off-road missions.  Some were also built for amphibious missions, outfitted perhaps with propellers or water jets. Of course, most APCs were also outfitted with some type of weapon to help fend of any potential attack..

MEDICAL APC USE

Some APCs take the form of armored ambulances. These are designed for specific evacuation of wounded personnel from the front lines.  These armored vehicles would be equipped, of course, with medical supplies and stretchers.  One of the most important—and interesting—aspects of the medical APC is that article 19 of the Geneva Convention states that “mobile medical units of the Medical Service may in no circumstances be attacked, but at all times be respected and protected by the Parties to the conflict.”  Of course, Article 22 also allows them to carry weapons, though they are unarmed most of the time.  

INFANTRY FIGHTING VEHICLE APC

The infantry fighting vehicle is a special type of APC that is designed more for combat than transport alone.  There are many different types of IFVs that can be deployed on the ground alongside both traditional tanks as well as other APC units.  Essentially, the IFV has a special designation as an APC cannot have a cannon larger than 20mm; if it does so, it must be classified as an IFV to provide additional fire support to infantry that has been dismounted.

INFANTRY MOBILITY VEHICLE APC

Mostly similar to the traditional armored car, the infantry mobility vehicle is a type of armored military transport which focuses on adding protection from land mines.  Primarily, the IMV aims to add protection among the more unconventional theatres of war.
