I notice in the aftermath of the parade that LY-1 naval laser has really caught people's attention. For lay people more than the UADFs the big laser has become the face of high tech weaponry of the parade.
It might be useful in future parades to have at least one such weapons that will really fire up the public's imagination even if it's unlikely to have major effect on the battlefield. Like say a square of robot wolves marching next time under their own power.
To achieve a similar effect they need to march troops with power armor.
