Ok
@pla-mkii i rated your post positive to appreciate your out of box thinking and the effort you share it all in that opening post. Much appreciated. It is presenting such ideas and then brain storming those ideas like this that lay foundations of a positive constructive debate on a public forum like ours. That is what we should all appreciate.
Now that said, there are MANY key points that you have missed or dare i say, got wrong in that post.
To begin with, it is not a new idea at all. Spaced armour and layered armour have been around for decades and have been used with a varying degree of success. Plus the thing that you have specifically mentioned, an inner armour to give protection covered with ERA which then have an exoskeleton so that the shrapnel from ERA triggering do not affect the friendlies nearby have two basic issues that need consideration.
Firstly, the weight of the machine. Tanks today form the spearhead of the attacking corps and are no longer fortified pickets that can move at snail’s pace. The modern tank formations will always be used to penetrate enemy defenses and lead the assault into enemy territories. In today’s modern warfare where surprise and speed are name of the game, you main striking forces need to be agile, fast moving, able to take a punch and still have enough left in it to strike back. Keeping all this in mind, 4-5 HEAVY layers of armour won’t be an ideal situation as it will make the tank too bulk and too heavy for sure. Talking about Pakistan specifically, we have a certain none declared weight limit when It comes to our tanks and we have seen some good systems not being considered jut because of their weight.
Second problem in this approach is related to ERA and for better and easier understanding I will further split it into parts.
- The ERA bricks are usually installed as add-on that can be put on easily and therefore, replaced swiftly in war zone once some of them have been triggered. Having them enclosed will create a maintenance nightmare as it will be impossible to access them in war zone (they will be covered by two layers of foam/absorbent material and an outer armour)
- The advantage of ERA add-on bricks in not just ease of maintenance, for a country like ours (and MANY others) the additional ERA bricks give a cost advantage as one can chose to install or leave it on some of the vehicles as per requirement. Having them boxed inside means they roll out of factory like this, each one of them. The cost goes up.
- The bricks, since individual blocks, can be replaced if some of these are used/damaged. It won’t be possible if these are boxed in an outer shell.
- The worst of it, once triggered, the ERA will explode. Since they are now in a closed space, covered by hard outer layers, the blast of ERA will make big chunk of that body armour (outer) flying (blast wave). Virtually destroying the outer surface, damaging any accessories installed on that part and posing threat to nearby infantry.
These are a few key disadvantages that one will have to consider and work a way around it while trying to follow what you have suggested.
So what is the solution, well there might be many and coming years will reveal them gradually. I am of the view that tanks are here to stay for foreseeable future and will keep being utilized as the spearhead of any striking force. One solutions coming out is in shape of APS and it is not just the hard-kill approach. The soft kill approach will keep on getting refined and more mature as time passes. Yes the threat level will also reach new highs but the defense mechanism won’t be far behind. The hard-kill mechanism have been proven quite effective with Israel already and again, will keep on moving on their development track (and are on right track as far as I can see). Electronic warfare will also be playing a key role in coming years and i think soft-kill APS will form the main line of defense, specially for dumb attack munitions.
A very basic relatively simple solution or risk reducing action might be something from the history books, an infantry square formation BUT with roles reversed:

Rather than having the infantry forming a parameter around cavalry to protect them, we will have cavalry forming the outer parameter of forward moving formation with soft vehicles and infantry moving inside.
View attachment 455439
The outer perimeter formed of APS equipped tanks will give a decent level of protection against any guided or dumb projectiles and with the modern electronic equipment and radars/sensor, the effectiveness of hard-kill APS will surely increase. Also since they will be forming outer layer, there will be minimum risk of flying shrapnel or kill explosion damaging own friendly forces since they will be on the inside of the formation.
