Nice guide, though you under value the assault group, when properly microed it essentially is a better armored, more deadly m3, with the possibility of having double shrecks making it a deadly surprise if a fragile one.
Thank you
I'm not going to say it's useless because I'm not prepared to say that about anything.
But I will say it's the least useful thing in the Commander and it's certainly not an efficient or timely substitute for teching to T2.
Rather it's something you should buy because you intend to use it.
When there were early T70s roaming it was a useful counter. These days I'm not so sure that are that many things out there by the time you can get it that it will be that useful against.
