There is a big difference between the Civ3 and Civ4 combat systems.
Units in Civ3 lost just HP, whereas units in Civ4 lose both HP and strength. Strength in Civ4 is much more powerful, but because of the way the new combat system works, injured units are still weak. This is honestly a beautiful solution to the problem.
Whereas it was hard to argue in Civ3 that wounded units represented a damaged unit (they still had the same strength) instead of just one with less people, in Civ4 the combat system represents this. Notice how tanks look kind of beat up as they are damaged? This damage makes them easier to destroy.

A military unit out in the field will disintegrate into nothing even if not in contact with the enemy. The civ combat system gets the overall "feel" more or less right without actually modelling things like logistics or single combat between units. You can't keep your units continuously in combat fighting everything that comes their way regardless of how powerful the unit is. When a badly damaged gunship unit loses to an archer I don't think of the helicopters actually being destroyed by the archer, just that the unit is now no longer combat effective due to you not properly maintaining the unit so it is removed from gameplay. To get it back, you have to build a new unit. It's called abstraction people, you'd think Civ players would understand that concept.
