True not easy to use but you can Substitute your add-on UK Forces.
Down load play with his Tutes and then go in and find the lines that have his guys rapelling and then Sub. the UK Forces in. Remeber the Title (UK Forces) my not be what the add-on maker Actually called in the add-on. I ran into that once or twice. Like F14-A was actually called usafa14 or something like that( inwhich you can sub any aircarft too).
Once you get the handle of
Snypir's Package, It is
Very Awesome and
Flexable esp for MP.
