[Armor] Why did mankind engage in a full-scale war against the ants without any kind of research into how the species actually works?

Was it because the ants attacked first and we had to make a show of retaliation?  Every mission just seemed woefully under-prepared with little to no intel.  Banshee did not seem to be our first fight against them.

The ants attacked Earth first. As for intel, what can they do? All the sensors fail constantly. The sand ash is metallic and constantly blowing and sifting. It's geologically very active and the damn bugs live underground. They have no idea what their society is like. They don't even know if there is a sentient leader or if they are a hive mind. Or they could be something else we can't imagine.

They are truly alien. They can reproduce like a factory line and even choose how they make themselves. They had several which were malformed and were like cheap knockoffs, just so they could ambush a base with normal ones. 

They even have the hammer. We never get a good explanation of how it works. Is it biological? They they biomechanical? It's likely. So what can we know before dropping on top of them? All the information they really have is from the Earth invasion and that is a much different scenario.
