This guy goes through all the different units and buildings that he finds important. I would suggest putting him on 1.5 speed, he's a little slow at talking.
I noticed the APC which i forgot about, and the flying version.
I can understand linking the wasps for carrying larger units only, but there's already a unit carrying unit, so my thought it why not just improve them with either more armor or faster speeds.
I was also reminded of the night vision mode for specific units. maybe we should change that to "heat" vision, or "electrical detection" so you can see units through landscape at a specific distance.
