Are the A-10 Warthog Thunderbolt II ground attack fighter jet and AH-64 Apache attack helicopter obsolete? The answer can be summed up in one (unsatisfactory) word: depends (or rather, it depends on the mission set). The nature of the modern battlefield is that it changes.Often, not only do tactics change, but so too does the role of some of the equipment. Military equipment needs to find a practical use on the modern battlefield, or it will become obsolete. This is perhaps why the A-10 Warthog is being retired while the Apache isn’t – the Warthog seems unable to find a new role while the Apache has.
