I think this surfaced on here before.
Although this is a larger version. I like the idea, but I'm just not sure how useful it will be.
Perhaps if you could fire from inside, and use it as a mobile gun platform or something. I wonder how many you can fit too, if it's only 5-ish i really can't see it having the right impact on a battle.
Perhaps they will have some sort of scouting group functionality, similar to markerlights maybe.
Time will tell I suppose, strange thing for them to add though.
