Strategies:-
The Hydra is a quick and agile GA supporter for fragile AA units like the Hawk and the Falcon. Employing their fairly medium range ballistic missiles(10-12), the Hydra can gun down enemy Air Units impending danger to other allied Air Units. Though it is not able to fire at ground troops, its ability to move fairly fast gives them the advantage in escaping from enemy ground units. The Hydra is also a good PoC defender as it can blast Rocs and such out of the sky when it comes too near for comfort.

GA support:-
Though lacking in range, unlike the Manticore, the Hydra makes it up with its speed and high damage. However, since it pretty speedy and can do around 500+ damage for a TL 111 weapon, it is a good supporter for as I said earlier, the Roc. Of course, some GG support would also be crucial in making sure that the Roc gets to the PoC on time and doesn't get blasted to pieces by a group of Owls or Hawks. Its best that a few Hydras and some other ground attackers are present at the PoC before the Roc arrives as they need to clear some of the defenders before the capturing of the PoC can start.
