This is the most iconic vehicle, aside from the supertanks Mike and Victor, that I designed for my comic 6-commando
. I owe a large part of this design in its present iteration to Jim Francis, I have to admit - he did a swell drawing of it on a guest page he drew for me years ago, and the edits he made to the design stuck.
The Howler is a ground-effect vehicle, what might also be called an ekranoplane or a lifting-body airfoil. In the world of 6-Commando, the United Nations uses Howlers as airmobile light tanks and reconnaissance vehicles. They can "sort of" fly - really more like a long, powered jump - and hover on direct thrust. They fill a niche in the UN battle line that doesn't exist in the real world. Probably the closest parallel would be a riverine craft, or perhaps the heavier helicopter gunships. But either way, the design is fairly sound, although not hugely useful in the real world.
