These are the three KMB coptas that I made to go paladin hunting. They did a great job, usually killing a paladin a turn until they got wiped out from retaliation shooting.
I also have two green barons, a squadron of five with the big shootas and five with twin link rockits. Just can't seem to find where I put the pictures. IF/When I find the pictures I will post them as well.
In this new edition, I have been using a squadron of three with the rockits, they out flank and then shoot some armor or other similar heavy support in the rear. Most times they then draw a lot of fire until they are dead, allowing the rest of my army to get in close and personal. On the few occasions when they get ignored they cause more mayhem by killing off various other heavy support choices that really hamstrings my opponents gun line attempts.
In a recent game against tau, they shot down the ethereals devilfish and the explosion killed off most of his body guard and pinned them. It was great fun to pin tau
Then a truck load of boys drove up and assaulted the survivors, earning me a warlord point as well.
