Classic Traveller Weapons: Grenades

My Auzhan Sector setting uses LBB 1-3 almost exclusively, with a few elements from later materials. 

 

I am borrowing Hand Grenades straight from Book 4. 

Hand Grenades: The modern hand grenade appears at tech level 5 and is generally available thereafter. Hand grenades may only be used against targets at medium range. One grenade may be thrown per combat round, during which the thrower is treated as evading. A player may elect not to evade, in which case a DM of +1 to hit is applied. No specific weapon skill is required to use grenades, but a required and advantageous dexterity level is noted on the weapons table. A basic throw of 7+ to hit is required, with no range modifiers used and the target modifiers of the Shotgun used. Additionally, the following tech level modifiers are used: Tech level 5 & 6: DM -2 (4D damage). Tech level 7 & 8: DM -1 (6D damage). Tech level 9+: DM 0 (8D damage). All grenades are thrown at a single target and use the Additional Damage from HE Rounds rule.

All grenades weigh 1 kilogram and cost CR 200 for a case of 20. In addition to assault grenades (covered above) a variety of smoke grenades are available for signalling and obscuration, and specialised grenades (gas, anti-tank, etc.) are sometimes used. Referees must devise specific rules for the use of specialised grenades.
