Ok first off, the cost of mammoth is fine. You dont pay for health people. It costs the same as it does in Tiberian Dawn and this game is basically that but on the ground right?

ANother thing. The mammie has a grand total of 4 weapons, 2 gun turrets and 2 rockets. YOu fire at a sligtly faster rate than the med tank because it switches turrets every shot. It may be slow but it has 400 more Health than the 2nd highest health unts flame and medtank. It carries more firepower than any other unit on the battle feild. I think it can also out run infantry.

Last but not least. mammie drivers have to be smart about what they are doing. They gotta watch their backs, they gotta see wat is shooting at them and from where. If a mammie can locate its target, that unit is screwed over. Mammies work well when they got differnt tanks other than other mammies supporting them.

I posted yesterday about how a mammie and med tank took out the obalisk by themselves. It should be on page 2. But its quite enlightening, on how the 2 of us did it.
