I have been playing with this one for quite a while and so far have really liked the idea. I cant remember if I posted this before so I figured I would (re)post it with the new numbers incase I hadent already. This weapon evolved from wanting to see a decent machine gun type for lighter mechs. Im hopeing this isnt over kill, but give me some input. I tried to make it believable and somewhat realistic for battletech purposes.


Avenger Mk2 High-Velocity Cannon.
After a extended trip to Terra the well known Doctor Banzai and his team came back with the blue prints for a interesting new design for a cannon. Based on the ancient Avenger cannon mounted in the old Terra A-10 Warthog ground attack aircraft, they set to work recreating it for battlemech, vehicle and Aerospace use.

Avenger Mk2 HVC
Weight: 4.5 tons

Range: 6-12-18

Damage: (5) 15* (30)

Heat: (6) 12* (24)

Ammo/ton: 100

Weapon BV: 310
Weapon V: 79
Ammo Value: 39
Cost/ammo: 175,000 / 12,000

Game notes.
the unique design of the weapon allows for a higher rate of fire. The weapon has the ability to alter its firing modes, it can so with a short burst that can cause 5 points of damage (roll for locations like normal) it can also do a standard burst of up to 15 (5 points per location) or it can double its rate firing doing upto 30 points per salvo. To determin how many groups hit consult the srm 6 table and roll to hit as you would if firing a srm 6 (note if firing a short burst roll to hit as normal, on a standard burst of 15 consult the missle table for a flight of 3 missles (pg31 in the master rules book) multiply damage by 5 and apply any damage in groups of 5 normally.

Ammo:
Ammo is done in rounds of 100. It also has one major drawback in that it contains so many rounds that CASE (both 1 and 2) are useless when a ammo bin is hit. Half ton units are avaliable but the same restriction on case applies.

Heat:
The weapon produces 12 points of heat ever time a standard round of 15 points is fired. when it is doubled it produces 24 points of heat. on short bursts of 5 it produces 6 points of waste heate.

If the weapon is hit with any damage it is considered destroyed. There is also a chance that the damage done has the chance to set off the ammo (roll 2d6 10 plus it goes off), if the ammo does cook off apply the current firing mode damage to the internal structure (example: if a 5 point short burst is fired that round when the weapon is hit and the ammo cooks off then apply 5 points of damage to the internal structure and calulate damage normally).

The nature of the weapon does give a -1 to hit but it can not be combined with a targeting computer of any kind.

Due to the heavy vibration caused by the weapon the following rules apply to creation. Any light or medium unit (mech, vehicle, or aerospace) may only mount 1 Avenger. Heavy and assult units may mount no more than 2.

Ok I hope this isnt overkill since damageis rolled on the lrm chart and applied in groups of 5, I think it balances it fairly well. Anyway let me know what you think. My biggest fear is that it seems to have a lot of record keeping to it.

And here is a mech example to go along with the weapon.
