"This is the simplest way to win against computers and some people using House Atreides. I don't suggest using it more than once every 5 minutes. What you need is an Advanced Carry All (known as ACA), Mongoose (2), Sonic Tank (if wanted), Repair Car,

Minos, and some infantry. The first thing you do is move all of those units close (not too much) to the enemy base. Next start disturbing the enemy with the infantry only. Now load the ACA with the other units and carry them to an open space in the enemy's base. Now the enemy is helpless unless they use the palace attack." - ZT

"In Harkonnen missions which involve killing a large group of infantry (i.e kill the Sardaukar general, destroy the Tleilaxu base) simply build a mid sized group of buzzsaws (5-10 should do) and run the group over to complete the objective in the first few minutes of the battle." - goatsucker

"The Atreides Minotaurus is undoubtedly the most effective unit there is. I believe that most maps can be completed by by a team of these long range units, some repair cars and a few (10 or so ornithopters). Here's how:

For the first stage of the game, defend your base with whatever units you can while you build up your minos. Place each mino around your cliff edges and put some out on your main entrance. Make sure they are equally spaced and in a line if possible. Make sure they are continually repaired. If they are attacked by Inkvines or Cobras, call in the ornithopters. They will slowly obtain chevrons. When one has achieved three chevrons, move it back to allow others to build experience.

Slowly inch your minos forward, capturing objectives as you go. Force fire on infantry rock to clear any fremen. You ultimately want to end up laying siege to the enemy. You will kick ass if you do this." - Wee Bastard
