He's a recon/surveillance specialist and sniper.
Warren didn't like his role in the team when first assigned to him,
Especially when Scott explained to him that with out learning these skills he was useless to the team. 'What use is a guy that can fly in a fire fight, you're not super fast so if you attempted to swoop down and attack some one they would see you a mile off and have plenty of time to shoot you out of the sky, but at as a long distance fighter and the real time intel you can provide us on the ground you would be invaluable to the team'.
However once Angel threw him self into training he excelled at every thing and as a result became an indispensable part of Scott's team.
Hank equipped Angel with everything he could need in his role. The head gear provides Angel and the team with Telescopic, night , and thermal visions. enhanced audio and video recording and a multitude of tracking options. The mask can also provide Warren with air if he needs to fly really high to avoid detection. The rifle has stun, kill and explosive options.
any hoo that's all for now
