The Specialist Class in XCOM 2 uses a remote-controlled airborne called as the Gremlin which not only provides team support, but also objective and enemy control.
With the use of the flying Gremlin, the Specialist Class provides support in terms of healing, support buffs, remote hacking, and boosting stats. However, one thing that you need to know is that the Gremlin must be guided by the Specialist as his action move for a turn.

When it comes to weapon, the Specialist Class only excels when equipped with rifles. As for Class Abilities, the abilities mostly revolve around improving the functionality of Gremlin in multiple ways.
XCOM 2 Grenadier Class Tips
Needless to say, but the Specialist Class can provide plenty of support in a fight, therefore; it is a good idea to stick behind cover and try to stay alive for a few turns.
It is also important to note that the Gremlin action do not end the turn automatically so you should consider boosting HP or defense of an ally while continuously firing for the turn.
You should also consider getting your hands on the Medical Protocol as soon as possible as it will allow you to provide support remotely.
While it may not sound much, it will save you the trouble of heading in the middle of field in order to revive a downed treatment. Moreover, you should also upgrade to the nanomedikit whenever you can.
In XCOM 2, the Specialist Class also has the ability to send in Gremlin to a nearby turret or CCTV in order to bring up the hacking screen. While you will get slim chances of a successful hack, you should definitely try your chances.
If successful, you will get your hands on a random enemy unit on the field and takeover enemy turrets. However, you should also bear in mind that a failed hack will destroy your concealment.
When it comes to abilities, Field Medic and Medical Protocol work really well by providing you with a total of 4 charges and remote healing. Moreover, the Haywire Protocol allows players to gain control of an enemy turret for the rest of the mission.
Lastly, the Scanning Protocol can be used to locate civilians as well as shape-shifting enemies hiding in plain sight. The class abilities in details are provided below:
