nice and handy did mine to some time ago, but I leave it open on the back so its easyer to remove casulties and is your unit might get bigger you can take an other movmenttray turn it a round and slide it at the back of the unit easly getting some extra ranks.
I'm a dark elves player so for my corsairs I rampage the sprue with my hoddy knive turnig into some the wood of the deck and it works great.
best of al its cheap and you chose your own sizes.
and by letting a piece open in front you can put some extra's on it like a rock or a skull or two.
anyway thx to share it with the rest cause I'm to lasy
