Making a Orc Burrow work for Other Units...

-sigh-
So I worked on this for most of the weekend, but alas.. I'm a little rusty..
(Maybe more so that I want to admit)
Anyway: I have been tring to change the Orc Burrow to work with a modified Rifleman, instead of a peon. Any help will be thanked!

[Note: Sorry if the answer is elsewhere, or if this belongs elsewhere.]

You have to edit the unit type on the "battle stations" ability. The burrow should have, besides this ability, also the Stand down and the cargo hold ability.
