While waiting for my dentist appointment yesterday, I was reading through War Dept Tech Manual TM9-219 (Basic Aircraft Machine Gun Cal. .50, M3) I saw a reference to a round listed as "cartridge, tracer, headlight, M21). The book gives no other real info on this round. It was listed in the ammo section as having a red tip, like the tracer, M1. and shows to have similar ballistic properties as the the other tracer rounds.
Does anyone have any info on this? IS it just a brighter tracer compound?
Thanks in advance.
I'm off to dl the PATCH!!

Google is your friend...
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Most tracers have dark ignition and only glow after they're a little way
from you: makes it harder to pinpoint the exact source. Also, some types
have low visual signatures but are very bright in IR: used by helicopter
doorgunners wearing night-vision goggles, among others.

Finally, there's the 'Headlight' tracer, designed to be bright and
visible from head-on; developed during WW2 for bomber gunners, to make
their defensive fire more deterring to the enemy. <HR></BLOCKQUOTE>

DUE TO ITS BRIGHTNESS AND SMOKE TRAIL

Maybe that could explain why some M2 guncam footage has conspicuous smoke trails, and others do not?
