Wings to carry paratroopers.....

[K_Johnston]

What he means is, a reg force unit probably isn't that worried about having their 'wings' discovered lying around because they will probably be an arm of a much larger attack, and will probably be making a lot of noise themselves. A special forces unit on the other hand is most likely hoping to complete their mission and get out before anyone realising that they were ever there. Having to hide a 6 footwing would then be a problem. An even bigger problem would be trying to lug it around with you!

Thank you, you explained it a lot better than I did.  That is exactly what I meant.
