COB timeline (ARMFRT.COB)

• 0.40–0.70 s — AimPrimary(+45°, +20°): turret y at 250°/s, gun x at 250°/s (target = 0−pitch).
• 1.20–5.20 s — 3-shot salvo at the weapon's 2 s reload (ARMRL_MISSILE — the NS variant fires the SAME def). FirePrimary only advances the shot counter static0 1→2→3→1 — the launch flash and smoke (startsmoke=1, soundstart=rockhvy2) are ENGINE effects; the COB hides the flare piece at Create and never shows it again.
• 2.20 / 4.20 / 6.20 s — re-aims track the target (+24°/+28°, then back) — and carry the barrel ratchet: the missile pack rotates to the counter's position (0° / +120° / −120° at 400°/s) = the classic per-shot mechanical indexing (3 positions, counter resets after shot 3).
• 6.20–6.60 s — AimPrimary(0, 0) back to rest (no RestoreAfterDelay in this COB).
• RockUnit (naval) — the engine rocks the floating base on the waves (base x/z overshoot + settle at 15/12/3 deg/s, arguments from outside) — engine hook, not part of this loop.

There is no RestoreAfterDelay in this COB — the turret stays aimed; the loop's closing AimPrimary(0,0) is the call the engine would send next.
