dune2k unused content?

[Striking Drekavac]

since there was some unused content in other westwood games what about dune2k?

was there any content planned for dune2k pre-release and was removed on final release?

i assume something was because  when was working on my mod i found few weapons that were never used

 

Hydra
Bullet14
non homing rocket

mtank sec

 

from my knowledge the hydra would be aerial bombardment weapon like airstrike since hydra were actually missiles.

bullet14 probably another infantry weapon

non homing got no idea but maybe something like  ww2 non guided rockets?

 

mtank sec is flamethrower.

 

also we have small gun turret then medium gun trret and then large gun turret. did the small one was  deleted ? perhaps the bullet14 was designed for that one?
