A video that shows British troops firing at a poster of Jeremy Corbyn has been labelled as "unacceptable behaviour" and a "serious error of judgment" by Brigadier Nick Perry. He added that what is shown in the video falls far below the behaviour expected of soldiers in the brigade. Report by Thomasl.
