This is my first SWBII creation and this is the Dark Trooper's jump pack. In battlefront 1 and 2 the jump pack is the opposite of the jetpack. Jetpacks allow one to fly in all directions controlling where they fly. A jump pack sends you into a parabola (or Arc in non mathematical terms) shaped jump. This will allow you to cross the battlefield even quicker than the jet pack.
In battlefront only the dark troopers are armed with them. The pack itself is approx. 16 inches tall by 10 inches wide, so any Moderately to large person will be able to wear it. However the pack comes with no body attachments. So it would need after market, non lego attachment pieces. It also comes with the exhaust for extra detail.
Enjoy my very first Lego Battlefront equimpement piece.
