Engine of Destruction Speed Run on Brutal Difficulty - SC2

Brutal Difficulty Speed Run - Time done: 22:40 - Completed all mission goals and achievements on brutal. I killed the Loki for the "Kicking Asgard" achievement, and I didn't let the Odin drop below 30% of its total health for the "Ragnarok & Roll" achievement.

Tip: Remember you can drop down MULEs to repair the Odin, and Science Vessels can repair it too.

NOTE: After this mission I do the following upgrades and purchases:
ARMORY: I purchase Ripwave Missles and Phobos-Class Weapons System (for Vikings).

I beat this in 20:01 using nothing but fully upgraded ghosts. I let the Odin take care of the first base by himself, only sending scvs to repair him after he's done and I made a single science vessel and made it follow the odin. Then I destroyed the rest of the bases ahead of the Odin. At the 2nd base the only detector is a single raven. Just pull it out and kill it by itself. 3rd base has a single turret in the back. Same with the last base.

I cant make Sciene Vesselse, neither that or BCs like a read other players can make in this map. How can that be?
