Here's something I never saw before..

[Nathangun]

This is during the Drums of War battle with @Boce
An infantry team were caught out in the open and were ready to surrender when this happened....

They rallied when other troops caught up with them and it wasn't a HQ unit.

Hi Nathangun, I don't have seen nothing special in the video, when some troops surrender, if the enemy arrives, they take the white flag and dissapear, but if arrive before friendly forces, they take up arms again.
Maybe your morale is low, be carefull with that.

 

[Nathangun]

That's exactly it, my guys had their hands in the air ready to surrender then other troops arrived and they rallied.

I've seen this before. It doesn't have to be an HQ unit that rallies them. Simply the presence of friendly troops in near proximity will often allow them to rally.

Yeah it represents friendlies coming in to save their buddies before they are carted away. Always worth a stab to race some guys in if you think it's safe to stop your guys surrendering.
