Well I have an old Seleucid army and the armoured ellies there get (S) due to their escorts but while playing another ruleset that really mistreats elephants the thing started to annoy me. I just started collecting an Ghaznavid army and while getting further into their history it annoyed me even more, this time from both rulesets perspective, that armour has no effect - after all its much more costly to armour an elephant than to add some crew. Why would have been done if it wasn't significant?
I think all raise the question in the list as you proposed to get it addressed.
Hi John
Did you get an answer that made sense to you??
I got involved in the discussion and it went very wide and was often well away from armoured elephants.
I've done a lot of work on elephant warfare of late, albeit mostly in the SE Asian area, and I've come to the conclusion that armour on elephants make no difference, possibily even had a detremental effect.
You will notice that generally, in all areas where elephants were used and many of which didn't have contact with each other, that armoured elephants were very,very rare. Even those states rich enough to pay the exhorbinate price to armour them, didn't. Those that did seem to have done it for prestige and/or as a visible elite so it was for morale effect rather than battlefield results. Ghaznavids (of which I have a half built example) are one of those where (dispite their quite high outright numbers) the relative numbers to other troops and there concentration ratio made them a support arm rather than the main offense arm.
The full details are on the M2 List but in a nutshell my reasoning for discounting elephant armour in combat is that, apart from a very lucky critical hit, the beasts were basically immune to the missile weapons of the time due to the depth of tissue peneratration required to be more than a pin prick. And the same peneratration problem existed for hand held weapons except if you failed you most likely got crushed.
Even for unarmoured elephants the sole point of attack was to dispose of the crew, this was standard practise in all theatres around the world. The beast then wandered/was channelled off out of harms way where as was now undirected it'd seek food and water. Elephants aren't naturally agressive.
Basically tactics for dealing with armoured elephants were the same as unarmoured so the armour added nothing. If anything it may have made it slower and more vunerable.
In effect it was all for show.
Thats my opinion of course, treat as you will, but it is from a fair bit of grappling with the subject.
Cheers
