BRB Page 80 - "Aerial Support" states that Flyers must begin in Reserves. You would need a specific exception to this rule.
I believe this is the
FAQ Davall is referencing:
Page 80 – Flyers, Aerial Support
After the first sentence, add: “Note that special rules that allow an owning player to move one or more of their units into or out of Reserves after deployment but before the game begins (for example the C’Tan Shard Power ‘Grand Illusion’) cannot be used to move a Flyer out of Reserves.”
However, giving Infiltrate to a
DT flyer should give it the ability to Outflank when it arrives, making for good side-armour shots?
