G'day, all!
40K night at the LGS. 1500pts of Saim-Hann looking a little like this...

Facing off Grey Knights looking a lot like this...

The mission: No mercy.
Both sides deployed everything onto the table with zero reserves and the Eldar went first.

Brightlance fire from the CH Exarchs, Vypers, and Hornets reduced all three Imperial flyers to their lowest damage bracket. The 40 shots of scatter lasers from the two jetbike units took down the first flyer. No charges

All Imperial hvy weapons were reduced to five plus to hit. The Eldar lost one jetbike and two wounds from a flyer.

Eldar's 2nd turn saw the end of the last two Imperial flyers, two units of Palatin knights, there Warlord, plus one of the flyers exploded and took out half the other unit of Palatin Knights. Eldar also lost another jetbike from said explosion.

This being the remnants of the Grey Knights...

... the Imperial player conceded. Four Paladin Knights remained Vs two jetbikes destroyed.
Notes: I thought the Warp Hunter with the indirect fire of its S10 weapon would have been the key here, however, it was the Crimson Hunter Exarchs and the jetbike scatter lasers that won the day. Thank you Cavalier for the inspiration on the flyers. They were a hoot.
Nothing really had to be moved up. The Eldar could have just sat back and delivered the same damage, but that would have bored me to tears. The battle had gathered a lot of attention so I doubt the Saim-Hann will have such an easy run next time. I hope not anyway. Looking forward to the challenge.
Have just finished watching Star Wars The Last Jedi, so that's the reason for the"Imperials", comments instead of Grey Knights. Thanks for popping in and having a read... Pointy ears forever!!
