Is it possible to integrate knockback and impact effects with units, like being hit by an elephant or struck by a catapult? The Hyrule Conquest mod has this, but it's a fantasy world; do you think it's realistic? (And the units in the mod have animations for being knocked up and falling; if this is implemented, more animations would probably be needed.)

In case you will want it, these two are against Very Hard Aggressive AI, both playing with the Athenians. In the first one I outcompeted the AI on economy early game right at the beginning, then it seems I stopped paying too much attention to it. For the second one I’m only barely outcompeted in the first couple of minutes (I guess took a few seconds to set my dropsites, resources being far from the CC). I’m not using auto-queue anymore, to get used to how apparently most people play.  

Two things.  To let engine read your new tag in template (so that no error pops up), you need to edit the schema at the beginning of formation.js. To let the bonus really happen, you need to modify a few js, and you must understand the whole unit AI attack flow.
