Example: In a skirmish game the HD can approach and do its multi-shot ability. That alone should use up all of it's action points, because it does for human players. I marched 3X Dreadnought's and an Inceptor unit right up on it. It was able to still use 3 more actions and fire on the approaching units. I figured that the HD was done. Nope marched another Inceptor up and it fired a fourth time.
