I don't know about topgun ACM, but over the years I have learned that these skillz are probably the most important.
1. Ability to fly your aircraft while looking 99% of the time to your left rear, right rear, up left -up right-up middle
2. While in a weeds level flight, avoiding trees in front of you while doing #1.
3. While looking in the directions described in #1, paying attention to the other enmy hovering over your fight waiting for the pick, and being able to turn inside him when he dives down and augers.
4. While looking in the directions as described in #1, paying very close attention to your squadmate, as he hovers over the fight "protecting" you from other picktards while really waiting for the opportunity to steal your kill.
#4 over the years became the most important ACM I have learned and forgot, and relearned and forgot, etc......
5. Muting wrag on squadvox cuz his singing just plain sux... ACM not really...necessity - yes
