Making sure we don’t jump too far off the course of the thread - does armor need to be manned?
THAT was a home-run.
I have often wondered what we do with our surplus tanks. It is so easy, so very easy to convert them into unmanned vehicles with simplistic dodgem car type programmes that keep them going in a single direction, detection movement, or (now that visual imaging has made it possible) images, and opening fire, and continuing until the pre-loaded ammunition is exhausted, and then shutting down to serve as a live armoured outpost for infantry looking for a vertical foxhole!
Maybe armor is best replaced by highly mobile firepower that protects against what the infantry could bring in terms of anti-personnel weapons but leaves the rest off to be sacrificed in case something heavier comes up?
We There are available already
have infantry fire support vehicles offering 20/30 and 40 mm automatic cannon support. I don't know when it became legal to use these weapons in an anti-personnel role, but now that everybody is doing it, it seems to be the obvious axis of development for the future.
Rather than leave these unmanned, combining them with a battle taxi function might be more economical.
These are normally protected against 12.7 mm machine gun fire and shrapnel, that is likely to be the worst that can be encountered from a defending infantry.
In their fire support role, they do not pretend to do anything but hold down the heads of opposing infantry, allowing 'own' infantry to advance rapidly; however, the PLA light tank seems to be configured as some kind of tank destroyer, with negligible armour protection but either 105 mm, or 120 mm ordnance.
