Thank you, thank you, thank you thank you thank you!
WOW! I was hesitant to ask for a hint (because I really wanted to solve that one) but safe to say it would have eluded me if I tried for another million years. Your screen shots were perfect.
I'd also like to take this opportunity to say thank you to the creator, Jim Kindley, and all the brilliant minds who crafted the marvelous levels. Too many names to mention, but Mikulka gets a special shout-out (I'm still laughing about getting shot by mom's earrings).
LaserTank is a wonderful game.
