The land speeder is one of the coolest mini you can get when you play a Space Marines army.
I didn't want to keep the land speeder as it was "out of the box". This is why I added the biggest Dark Angel symbol I founded in front of it.
When I was preparing the land speedee, I added some magnets to be able to swap the second gun. I first painted the assault canon, which is a true Dark Angel gun... ^^
If you magnify the picture, you will see that these Doom Angels don't wear the same shoulder paldrons than the tactical marines.
I choosed to equip them with the Ravewing shoulder, painted in the Doom Angels colors: red sword, white wings. The other shoulder paldron is the fast attack symbol, with two crossed swords.
After many games (and almost as many explosions), I decided to modify the land speeder guns. I had to increase the fire range!
I supressed the assault canon (too expensive) and swaped it with a second heavy bolter. Magnet powa!
