In Zero Hour they have ABGDCTower models which have animated bones at the top.

For the assist weapon, make it have no laser so you don't see the assisting tower shoot, making it look like the first to shoot tower only is shooting.

Make the assist laser (not the weapon laser but the one for the assist data link) a regular straight laser and make it thicker than the primary weapon laser.

For the laser beam textures, check out the exlighteningtile1.dds exlighteningtile2.dds exlightning.dds

Here's a beam from the Tardis's weapon in my laser general mod:

Object LightningBolt
  ; *** ART Parameters ***

  Draw = W3DLaserDraw ModuleTag_01
    Texture = exlighteningtile1.dds ;exlighteningtile1.dds
    NumBeams = 1                              ;Number of overlapping cylinders that make the beam. 1 beam will just use inner data.
    InnerBeamWidth = 10                       ;The total width of beam
    InnerColor = R:200 G:200 B:255 A:200      ;The inside color of the laser (hot)
    OuterBeamWidth = 8                        ;The total width of beam
    OuterColor = R:0 G:0 B:255  A:10          ;The outside color of the laser (cool)
    Tile = Yes                                ;The height of the texture will determine how many times to tile the texture to fit without scaling.
    ScrollRate = -3                            ;Scrolls the texture offset this fast -- towards(-) away(+)
    Segments = 1                              ;Number of segments -- more segments give smoother curve (but more joints) Current max: 20
    SegmentOverlapRatio = 0                   ;This value overlaps(+) or separates(-) the segments by ratio
    TilingScalar = 0.3 ;.5 ;-3                ;stretches the texture if < 1
  End

  KindOf = IMMOBILE INERT

  ClientUpdate = LaserUpdate ModuleTag_02
    MuzzleParticleSystem = FlashBangNormal
    TargetParticleSystem = LightningFlareWithSparks
  End

  Behavior = DeletionUpdate ModuleTag_03
    MinLifetime = 260  ; min lifetime in msec
    MaxLifetime = 260  ; max lifetime in msec
  End
