User blog comment:Drayco90/Drayco90's One Year Spectacular: Terran Dominion vs. UNSC/@comment-1683193-20120606164634

Wait a minuite, Terrans get BATLLECRUISERS? The ones with nukes that can destroy continents? And Yamato cannons that can can pierce Protoss carriers Teraton level sheilds with massed volleys? Yeahh...this is such a fair fight.

Discounting the cruisers:

Basic infantry: Terran Marines have Gauss rifles and power armor whereas UNSC marines have basic rifles and flak armor. Andvantage: Terrrans by far.

Incinderay:Firebats have Power Armor and Plasma flamethrowers. Terrans.

Heavy: Marauders due to their range advantage.

Special Infantry:reapers due to their jetpack and chemical encancemant.

Elite Infanty:Ghosts can cloak, blow up skyscapers, hemorrage targets at long range, and have better weapons.

Basic Vehicle:Tie.

Tank:Siege Tank, seeing as it has more than double the fierpower of a scorpion out of siege mode.

Elite Tank:Grizzly. But on the other hand, Siege tanks could destroy them en-masse at longe range.

Elite Vehicle:Odin. While the EMP could potenetially do heavy damage, the Odin has a massive range advantage and could also handle entire squadrons of Vultures and Hornets. And then you've got to consider that Starcraft nukes tend to go into the gigaton and teraton range.

Gunship:Tied. While the Banshee is a much better land attack vehicle, the Hornet has better AA.

Elite Air:I'll replace battlecruisers with Vikings here. I'd give it to the Vikings because even though the Vultures better at Ground attack, they'd be easy prey for Vikings and the Terrans already have much better ground units.

But seriously, if you want to do Halo vs Starcraft, make it a space battle. At least then its somewhat of a fair fight.
