Since I study and teach Hapkido I can only comment on Aikido as a kind of "distant cousin". What I have seen is that even the people who train in Aikido don't have a clear appreciation of what they are learning.
If one trains in one of the earlier practices such as Shioda, Tomiki or Saito's variation there is a very clear sensitivity to training for combat. In the Aikido community itself, these variants are "frowned on" as rather de classe'.
Yet, when it comes to training LEO-s for the metropolitan police, these are the variations that the Japanese prefer.
Now, in the U S the practice of Aikido is more likely to follow one of the traditions coming out of the later years in Ueyshiba's life such as Tohei or Saotome. There is lots of talk of "Ki", "becoming one with the attacker", "compassion" and so forth. This is all well and good for New Age-ers among us. I should mention though that Bernie Lau Sensei a long time MA teacher, Aikido-ka and police veteran of many years has repeatedly spoken against high expectations for such traditons in combat.
As far as Hapkido goes, we get a lot of feedback that Hapkido people are to pre-occupied with "winning" and I cannot say that this isn't true--- just not in the sense of competition. As I mentioned before, the focus of Korean martial traditions is to restore the "Hwa" to the community. If I can do this by apologizing and buying a guy a drink, thats still good Hapkido. If it takes breaking a knee and choking a person out, there is that option as well. As far as multiple attackers goes, the rule is only use as much technique as is necessary to make good an escape. FWIW.
