Speaking of ramming speed, here is an excellent way to retreat in an Enforcer with Augmented engines.
1) Burn drive.
2) Fire rocket swarm (4x). They will fall behind and burn out.
3) Have your own rockets knock out your engines.
4) Coast away to victory!
Also amusing - I got hit by a hypervelocity asteroid yesterday
. Must have bounced off an enemy Venture when it was burning onto the battle. Spun my Medusa around and did 100 armor damage. It was kinda awesome, if a freak occurrence.
