It came as a surprise when I finally dig into the combat mechanics in detail and discovered that the "deadliness" had been greatly exaggerated unless one was shooting illegal military hardware at unarmored civilians.
If you mean that "illegal military weapons" like revolvers and shotguns have a 90+% chance of knocking out people in one hit is not all that deadly, sure.
An exotic TL-5 hunting rifle has a DM-2 vs cloth, DM-1 for Long range, and a DM+4 for telescopic sights, for a total of DM+1. Add a DM+1 for basic skill and perhaps even DM+1 for DEX 8+ to get a total DM+2(+3?), hitting on a roll of 6+ (72%) [or 5+ (83%)].
With a ~90% knockout on hit, the total mission kill is about 65% [75%] per shot.
Two armoured riflemen shooting at each other have a 88% [94%] chance of ending the combat the first round, by knocking out one of the combatants.
A shotgun has a DM+5 against unarmoured, DM+3 at Medium range, for a total of DM+8, so hits at a roll of 0+ (100%). With a knock out chance of ~98% it has a total chance of knocking out the target of ~98%. With Group Hits it attacks up to two other adjacent targets, so knocks out up to three targets (average 2.94 mission kills). Not at all deadly, I'm sure...
A barbarian wielding a Broadsword has a DM+3 at short range, DM-4 for battle dress, and DM+2 for skill, for a total DM of +1, so hitting on 7+ (58%). With 4D damage it has a knockout chance of ~98%, or perhaps 95% against a very fit soldier. So the barbarian has about 55% chance to knock out a battle dress trooper in a single blow. With a sword.
I guess Broadsword counts as "illegal military hardware" and battle dress as "unarmored"?
Actual "illegal military hardware" like, say, a Gauss Rifle has a much higher kill chance.
A Gauss Rifle shooting at battle dress has a DM+5 at Long range, DM±0 vs battle dress, and say DM+0 for skill, for a total of DM+5, hitting at a roll of 3+ (97%). 4D damage is over 90% knock out chance. It attacks three times on the primary target, and up to four other adjacent targets at DM-3 (72% hit).
Each primary attack has about a 90% knockout chance, so surviving all three is about 0.1% chance. If all three attack hit (91%) the target takes 12D damage and is almost certainly dead.
So, the attack has a 99.9% knockout chance, well over 90% kill chance, and knocks out another ~2.5 adjacent targets.
Is a 90% kill chance against battle dress considered "deadly", or is that "greatly exaggerated"?
An LMG firing at BD at VLong is DM-3 for BD, DM±0 for VLong, DM+2 for skill, for a total of DM-1, hitting at 9+ (28%). One burst is three attacks on the primary target, so about 63% chance of hitting once or more. With 3D damage against very fit soldiers (attr ~9) it has a 74% knockout chance. Total about 47% chance to hit and knock out.
Firing 5 bursts, it will knock out an average of 2.35 BD troopers per round, and perform up to 20 secondary attacks on adjacent targets, knocking out another BD trooper with a bit of luck.
Is knocking out about three BD troopers per round with a man-portable TL-6 weapon enough to be called deadly?
