I really agree that is was very lazy of them to use the M41A Pulse Rifle design as a basis for the Storm Rifle. They should have used this (FN F2000) if they were so lazy:
Two-person transport vehicle with 4-tread, track-belted wheels able to negotiate near-vertical terrain carrying small payload. With the NR6, Weyland planetary engineers are able to survey previously inaccessible areas of newly discovered proto-colonies. Vehicles reach top speeds of 88 mph in standard atmospheric pressure and gravitational pull. Variable-friction axes for front and rear wheels provide micro-torque gear adjustments for maximum safety and mobility across any foreign surface.
Hmm... Wonder if it has a Flux Capasitor...
