I was having a walk the other day and thought about what tactics the Guard could use against the Tyranids. Now the normal thing seems to be to have a massed frontline and blast away but I thought that I would suggest something different. I put it up here to get some respons before I use it in my own game. The idea would be this.
First established a series of strongpoints, heavily fortified, that can give fire support to each other. Then behind this series of mini-fortresses a proper frontline is made with artillery in support. The basic idea is that when the Tyranids attack the strongpoints will result in wave-breakers and from it artillery can be directed against the aliens. As I envision it the Tyranids can do one of two things.
1. Attack and crush each stronghold in turn while under constant crossfire from the other strongpoints nearby. The benefits of this is that the Tyranids will have to crush them each in turn and cannot make on breakthrought and then spread out in a killing spree into the trenches/lines and can only kill the men inside one stronghold at a time.
2. Rush straight through at which point the Tyranids will be subjected to a crossfire the like would stop them dead if anything can.
3. Do both things at once which could overwhelm the defenders but more like it might make the Tyranid attack more splintered and perhaps to weak to break either one of the two targets.
Is this a suicidal idea or could it have some merits?
