3. When lining up for battle, the most experienced soldiers are in the front. This could be because the order of soldiers in each unit never changes except by death/reforming, or it could be because the game rearranges them. The precise reason is unimportant - all that matters is that the high XP guys tend to be in the front for most melee units.
Now, imagine a battle taking place. The front ranks meet in melee. These are highly experienced soldiers, more experienced than the rear ranks. Every time one of the highly-experienced men dies, the unit's average XP actually goes down, although you won't necessarily see it. As the experienced men die, they are replaced by the rear ranks, who get some kills, thus get some experience, and overall the XP of the unit stays about the same, or increases only slowly. If you win the battle, sometimes some of your casualties will come back to life - typically that means high XP soldiers returning. That is why you will often see units "jump" in experience right as the battle ends. However, if these high-XP casualties stay dead, it is tough to actually improve a melee unit's experience.
Now consider the slingers - they ALL fire their bullets, so they can all get kills (not just front ranks). The experience is more evenly distributed across ranks, and they also typically die less. Slowly but surely, they will build up XP (and usually quickly and surely). For this reason, slingers are actually overpowered a bit - not because of their stats or AP bullets, but because of the XP mechanic of the game.
