In order: Laser Carbine, Snub Pistol, Gauss Rifles (from the minis), and the ubiquitous FGMP-12 (which the group that introduced me to Traveller had an entertaining nickname).
Which cannot be shared in polite company, I presume?![]()
Who said we were polite?
I used to (still do in principle) have a rocket pistol IMTU. It was originally inspired by the Pyrrhan's guns in the Deathworld stories ('fires rocket propelled explosive slugs'). There's also a carbine or SMG firing the same ammunition.I always liked the Accelerator Rifle concept, and was surprised that this was actually a real thing, Gyrojet weapons, a few were used in the Vietnam War rather than in Zero-G, popularised by James Bond.
.50 cal M-60.
It's about 15mm of RHA according to the armour table, which is not unreasonable given that the .30-06 M2 armour piercing round is normally described as capable of penetrating around 1/2" of RHA at short ranges.[ . . . ]
Doing a continuing deep dive into the Striker rules, it struck me this past week that the ACR 9mm DS round has the same penetration (and therefore damage probabilities) as the .50 cal M-60. That's a LOT of punch in a 20-round personal rifle.

A .50 cal SLAP round is normally described as being able to penetrate about 30mm or of RHA at short ranges (500m IIRC but my google-fu fails me), which would roughly equate to a penetration of 12 at effective range.
When I did some rules for HMG AP round (back in the late jurassic period) I did stats for KEAPER rounds (think something roughly analagous to the Raufoss mk 211 I assumed it to have a penetration around 10, with a full-fat AP round (equivalent to the SLAP) having a penetration of 12.
A penetration of 6 is reasonable for ball rounds.
Back to the ACR, the stock Integration with Traveller rules make some weapons quite overpowered - 24D or more from a single attack with a gauss rifle is not unknown, even against targets wearing mid-range armour like combat environment suits. I used a couple of house rules to nerf some of the excesses:
- Positive bonus from an armour piercing round (gauss rifle, DS rounds, HEAP rounds from a snub pistol etc.) is capped at half the round's penetration. Therefore, a gauss rifle is +2 in total (+7/-5) against cloth, but +3 against an unarmoured target (half of +7 - you can round up or down as desired).
- Certain weapons don't get the 'exploding round' rule, in particular laser carbines/rifles and HEAP rounds from snub pistols or equivalent.
I also did some more detailed rules for generations of KEAP and HEAP rounds, to get penetrations of autocannons and CPR guns in line with modern (TL7-8) capabilities, and accommodating a few more incremental advances in the tech. This let one build a medium or high-velocity autocannon with a capability that's roughly in line with actual kit like 20x102mm AP rounds (approximately 50mm penetration at 500m) and so forth.
I believe using Striker discounts, you pay fifty credits for an automatic rifle, making it the ideal general issue weapon.
A .50 M60? The M60 I fired while in the military was 7.62mm, aka .308 NATO, and slightly less powerful than the .30-06. Now, the .50 caliber that I fired was the M2 Heavy Barrel, which could be fired semi-auto as well, while the tank gun I fired was the M85, no semi-auto option. I did not have a chance to fire the .50 caliber spotting rifle on the 106mm Recoilless Rifle. That did use a totally different cartridge than the machine guns.
Have fun trying to fire a slightly over 12 pound rifle, using a 154 grain 7mm projectile at 2,953 feet per second, in full automatic fire. I understand that a discarding sabot round is going to be lighter, probably on the order of the .30 caliber Accelerator Round for firing a .223 projectile from a .30 caliber weapon. However, discarding sabot rounds tend to be very hard on the rifling of the gun barrel, and you do have the discarded fragments of the sabot flying around in front of the barrel. These fragments are not going to be appreciated by any near neighbors slightly in front of the firer.
I figure the BAR, Browning Automatic Rifle, at 23.5 pounds loaded with magazine, the loaded magazine weighing 1.43 pounds, or the British BREN gun, are the lightest full-automatic weapons capable of accurate fire. Note, the BAR did have a semi-auto option, as well as 2 rates of fire. The M14 Modified for full-automatic use was lighter, but not at all liked as controlling it was extremely difficult.
