I agree with RK and Gorton, no reason to invent and use custom grammar.
Now, a comment on the content:
"Houses Commander. Combination of Barracks and Command Center. Contains all the blueprints necessary to build a basic army from scratch."
I dislike the blind reference to barracks and command centre -- does it mean the ACU produces footmen? Enables tech upgrades (sure does, but not the only thing) etc..?
"Increases Rate-Of-Fire to 250%"
Annotating 2.5 projectiles/s as 250% doesn't make sense to me. I'd prefer simply "Increases firerate to 2.5 projectiles per second".
Lightly armoured fast-moving harassment unit. Poor in direct combat. Can fire from flying Air Transports.
While harassment is something players often say about raiding, I don't believe the word belongs in a unit description.
