whats up with advent troops

[Azrell]

I keep losing missions due to having advent soldiers contrarily locking down area with overwatch. When i started looking at how they moved and took actions closer i started to notice something. Shooting does not end the soldiers turn. They are moving up shooting then overwatching. Whats up with that? seems kinda cheap and more than a little anointing. any one else noticed this happening?

It's a special ability of the blue Sentry/Sentinel troopers. Others like the dark-green Gunners, Scouts, regular Officers, etc. etc. won't do this.
