The ARM-ANS — Adv. G&N Const. Seaplane — builds ground and naval units. Its hatch opens and the two nano lasers extend toward the work site, then the craft swivels 30° clockwise, works, and returns. The wing morph is COB-exact (1:1 from ARMANS.cob: wing1 +5.59 elmo / wing2 −5.65 elmo slide, 1042 ms); the nano extension and the 30° swivel are construction choreography — in game those moves are engine-side (the nano spray and the aim toward the build site), drawn here with the stated values (pods 4 elmo forward, swivel sign verified against a render grid: clockwise seen from above).

COB timeline (ARMANS.cob)
- 0.00–0.40 s — Rest — hatch closed, nano lasers stowed
- 0.40–1.44 s — Hatch opens — wing1 +5.59 elmo / wing2 −5.65 elmo slide (COB activatescr, 1042 ms)
- 1.44–2.24 s — Nano lasers extend 4 elmo forward past the nose (construction choreography)
- 2.24–3.04 s — Swivel 30° clockwise toward the build site
- 3.04–4.04 s — Construction hold — lasers working at +30°
- 4.04–4.84 s — Swivel back
- 4.84–5.64 s — Nano lasers retract
- 5.64–6.68 s — Hatch closes (COB deactivatescr, 1042 ms)
The wing morph in activatescr/deactivatescr is the entire compiled motion of this unit — the nano spray and aiming are engine effects. The extension and swivel phases above are preview choreography with the stated values; the 30° direction is clockwise seen from above (render-sign grid + matrix check). Loop closes at 7.084 s (pixel-identical seam).
