That sounds an awful lot like, sure, we know it's ahead of it's time, but we had our super-weapon first, and you can't have one.
Not really, no. You're just hearing what you want to hear.
The autocannon existed in 1913. A beltfed 20mm autocannon also existed during the first world war. (Though the war ended before it could be used.)
Hell, the autocannon itself was invented in 1890, more than 2 decades before we designed it.

Glad you have your inspiration.
And yet we are not having its effect at any time of the day.
You are. You stopped the Arztotskan advance in the Desert despite being continuisly bombed.
1. We have the Tiger. Our logistical problem of the rhino mainly depends on how well we can defend our forward ammo dumps.
This is not a logistical problem. You simply don't have enough hands to fire the weapon. Also, those ammo dumps are being bombed. Don't worry, you are returning the favor.
2. As manpower is never a consideration, High alpha weapons should be of some advantage. We can just use human wave attacks against those armored cars.
Manpower is a consideration.
It doesn't matter how many different types you have, as you'll still only be making a total number of guns enough to equip everyone.
Aside from that, our cheap artillery provided no benefit, as we had enough when they were expensive.
Feel free to utilize human wave attacks against the APC's, but then don't complain because all your soldiers are shot down by infantry as they only have a shotgun or 5-shooter to defend themselves with.
3. Not to mention that you are building a wheeled vehicle. Desert, heavy, and high mobility isn't a valid combination.
It's not heavy. And you know, your defense relies on these highly mobile vehicles. Be careful before saying those should be useless.
4. Its armor is weaker than most modern armored cars (for the VIPs, not for fighting). HE shells should be reliably denting if not beating 10mm armor.
It only has 10 mm armor in the rear. It has more armor than your tank in front and on the sides.
It ended up being this:

It did not. The Davis gun weighted a 100 kg, and was utilized solely on planes due to it's size.
This is a rifled tube designed to fire a 2.2 inch shell, without creating significant recoil. It is five feet in length and portable by a single man, weighing about 25 pounds, but sits on a tripod to fire. The recoilless effect is achieved by firing a "wad" of rubber-lined cement, equal in mass to the 2.2 inch shell, out the back of the rifle. Tubes are manufactured loaded, and discarded after firing. It is accurate out to medium range. It fires the normal variety of artillery shells. Costs 2 ore.
