Below are my suggestions for how bullpups and carbines could be successfully implemented in ONLY WAR.
This assumes that carbines are simply a varient pattern of the parent weapon (in this case the lasgun), and that bullpups are a more advanced carbine.
Carbines are shortened versions of the parent weapon designed to reduce the footprint of the weapon upon the soldier - making it lighter, easier to carry and manoeuvre in confined areas.
Bullpups are a further development of the carbine where the benefits of the weight and manoeuvrability are retained but without the loss of range and accuracy that a carbine suffers.
With all that in mind here is how we utilise the idea of these weapons to enable more variety and viable options to the player while still holding true to the imagery and conceptualisation of what the average gamer considers a "carbine" or "bullpup":
Bullpup
- reduce the weight of the weapon by 10% ,
- give the weapon the close combat quality,
- give the weapon the unusual layout quality.
Carbine
- reduce the weight of the weapon by 20% ,
- give the weapon the close combat quality,
- reduce the range of the weapon by 50% .
Close Combat
The weapon is designed for use in confined spaces and thus can be more easily and quickly brought to bare on a target. The character receives a +5% bonus to BS when making a Standard Attack with this weapon.
Unusual Layout
The weapon has a configuration uncommon within the Imperium and those unfamiliar with it find it awkward to operate. If the character does not have this weapon as part the character's Regimental Kit the reload time for this weapon is increased by a Half Action.
Design Notes
These observations and ideas are the result of playtesting ONLY WAR within our gaming group of 20+ years gaming experience, with the additional input of an Australian Army rifleman with 5+ years experience.
We have found weight considerations to be a legitimate issue for an Imperial Guardsman so every 0.5kg counts, as it can mean carrying that extra clip or grenade in your Assault Kit.
Also, in-line with these standardisations of the carbine, consider a shoulder-stock upgrade for pistols:
Collapsible Stock
The weapon has been fitted with a folding stock so as a Half Action it can be turned from a Pistol into a Basic weapon (or vice versa). When acting as a Basic Weapon the weapon gains the close combat quality. Increase the weight of this weapon by 0.5kg .
Applies to: Any pistol.
