The A-10 Thunderbolt II is amazing. With a GAU-8 cannon that can fire 30 wine bottle sized rounds per second and Maverick missiles ready to blast down all opposition, this aircraft is perfect to fight terrorist groups because it can resist damage and does not need to fly fast because terrorists do not have easy access to fighter interceptors. It can carry up to 16,000 pounds of missiles and bombs, making it perfect to destroy a large area in which the terrorists may be in, leaving nothing to chance.
That's exactly what it's made for. Decimating the enemy and depleting their morale so that they will have less will to fight and we will have less casualties, which will make us have higher morale, not to mention our power over terrorists. This is something not found in F-22s and F-35s.
