Tracers that burn, smoke that hangs

September 28, 2026 · feature

The rounds in the air were the last thing in the sky still built from bricks: yellow bars for tracers, see-through sticks for their trails, an orange plank behind every rocket. Not any more. Tracers burn, shells glow and leave their arcs hanging, and anything with a motor writes its path across the sky in smoke.

Tracers that burn

A tracer is a round with a pellet of burning compound in its tail, and now it looks like one: a white-hot spark wrapped in an orange glow, smeared along its flight the way your eye smears it. The flak burns redder. Against a noon sky a stream reads as warm sparks; at dusk it glows; at night it lights up the dark. On HIGH FIDELITY graphics the brightest of them bloom.

A fight two kilometres off still reads, as a scatter of sparks rather than a crawl of dashes, so you can pick a furball out of the horizon and go join it. There's still no team tint on the fire. You read who's shooting by where it's coming from.

A crimson Sparrowhawk with its wing batteries firing, streams of orange-white tracers reaching downrange past a Starfang jet and a twin-engine Ironclad, faint vapour streaks behind every round — Four fifties, a gatling and a chin cannon, all talking at once. Every round drags a thread of vapour, and every few is a spark.

The rounds between the tracers are still invisible, but each one drags a faint thread of vapour that thins away behind it. That thread now starts at your guns. From the chase camera your burst reaches out ahead of you instead of trailing back past the tail.

A salvo you can read

A battleship's shell is a turned steel round now, a tracer glowing at its base, and it leaves a thin chalk line hanging along its arc. The line lingers for a few seconds, widens and drifts on the round's wind. Watch a broadside go out and you can see all nine arcs at once, curving down onto the target, and read the fall of shot along them. A tank's round is smaller, and its thread is finer and gone sooner.

An Iowa-class battleship broadside-on with all three turrets trained out, thin white shell trails arcing across the sea toward a bow-on enemy battleship — A full broadside in the air: nine arcs hanging over the sea, and the reply coming back from her forward pair.

Anything with a motor writes in smoke

A rocket burns yellow-white off its tail and lays a grey rope behind it that tears up and thins within a few seconds. A missile's rope is thick and white and hangs much longer. It billows as it ages, drifts downwind and rises a little. It still works as a warning: you won't see the missile, but you'll see the white finger pointing at whoever it's chasing.

A cobalt Starfang breaking hard and punching a stick of decoy flares, each a white-hot point dragging its own thick white smoke trail, while a heat-seeker's long smoke rope reaches in from the left — Fox two, and the answer to it: a stick of decoys, each dragging its own plume, and the heat-seeker's rope reaching in.

Decoy flares burn as white-hot pinpoints, and by day it's their smoke you see: a fan of thick white trails hanging where the jet broke. At night a star shell burns magnesium-white in a warm haze with its smoke climbing above it, and the sea below lights up just as it always has.

A Warden infantry fighting vehicle's wire-guided missile a third of the way to a distant tank, its motor burning at the head of a billowing smoke trail that reaches back to the launcher — On the steppe, the Warden's missile lays its smoke all the way back to the tube.

On the water, a torpedo's track is a foaming trail of bubbles now, spreading and breaking up astern of the fish. Seeing it is still the easy part. Getting out of its way is the hard part.

The bangs at the end of all this are still the old chunky blocks. They're next.
