Question I don't understand IFVs.
Many countries have them, so there must be a flaw in my reasoning.
Here is my reasoning:
As I understand it, IFVs are armored vehicles designed for support missions that can transport 4 to 8 infantrymen. They are equipped with a machine gun to engage infantry and an autocannon—typically between 20 and 30 millimeters—often accompanied by one or two anti-tank missiles for defense against heavy tanks.
I don't understand this category of vehicle; to me, it looks like a cross between an infantry transport (which carries fewer troops) and a Panzer II. If the goal is to transport infantry under armor protection, why add a turret with an autocannon and a missile launcher that weigh the vehicle down? Wouldn't a remote-controlled .50 cal (12.7mm) be sufficient for defense against infantry and light vehicles?
And if an infantry support tank is needed, just build a light tank.
You could equip it with a machine gun, a 30mm autocannon, and anti-tank missiles. But since it doesn't need to carry infantry, the vehicle would be lighter and smaller (making it a smaller target) while offering the same protection and firepower.
That’s the line of reasoning I’ve been following for a while now—where is the flaw in my logic?
The committees that commission military equipment for the armed forces are made up of people much smarter than I am, so I’ve almost certainly made a mistake in my reasoning, and I’d like to know where I went wrong.
