.
Overview:
The Jawbreaker is armed with a single Kali Yama Weapons Industries Big Bore 
autocannon-20 and two tons of ammunition.  The entire system is enclosed in the 
'Mech's right torso.  Defensively the chassis supports 5.5 tons (74% coverage) 
of Durallex Light armor.
.
Consistent with CMCD's branding contract with Sony and Winston, the battlemech 
uses Sony MSF-21 communication components and manages its targeting information 
with a Winston Sidewinder system.
.
The Jawbreaker cruises at 43.0 kph (26.7 mph), maxing out at 64.5 kph (40.1 
mph).  It does not have any jump capacity.
.
The Jawbreaker is designed to give heavy, short-ranged, direct, fire support to 
light lances, or to provide cover fire for long-range support units when enemy 
forces begin pushing into the support line or send strikers to disrupt support 
operations.
.
.
Capabilities:
The Jawbreaker's primary capability is being able to place a big hit on its 
target.  It achieves this, but it also pays for its success in several areas.  
First, its maneuverability is well below average for its weight and class.  It 
is far to slow to keep up with light and most medium lancemates.  The lack of 
speed and jump jets inhibit it in its rear-guard role for fire support 
lancemates, too.  Attempts to use the Jawbreaker's heavy hit in a striker 
capacity have also failed because of the ‘Mech's lack of speed and jump 
capacity.  
.
Armor coverage is the second area sacrificed to the massive autocannon.  Most 
of the armor is dedicated to protecting the big gun, leaving the arm, leg, 
center torso, rear, and head armor thinner than recommended.  Thirdly the 
weight and space required for this mono-weapon design do not allow the 
Jawbreaker to carry any back-up weapons.  This problem is compounded by 
ammunition dependency.
.
In addition to these problems the vibration of the autocannon creates a number 
of problems for the battlemech and the mechwarrior.  The original prototype 
mounted the cannon in the right arm, but the recoil and vibration from the gun 
consistantly damaged actuators after three shots and ripped the arm off after 
four.  Moving the gun to the torso only partially solved the problem.  The size 
of the gun and its proximity to the cockpit result in some of the vibration 
being unleashed to the cockpit.  Veteran pilots compare taking three 
consecutive shots with a Jawbreaker's autocannon to surviving an ammunition 
explosion.  Indeed, in combat it is rare to see Jawbreaker pilot take more than 
two consecutive shots except under the direst conditions.  Those who have taken 
four blacked out.
.
The weapon's weight also puts a great deal of stress on the right hip and foot 
actuators.  The actuators must be removed and serviced/rebuilt every 600 
movement hours.  It is possible to extend their service life to 1200 hours by 
switching the left and right actuators if the ‘Mech is actively deployed rather 
than garrisoned.  Also, regarding maintenance, technicians have to check and 
tighten down every nut and bolt anytime a ton or more of ammunition has been 
expended.
.
.
Battle History:
No specifice battles will be cited.  However, the Jawbreaker has excelled in 
ambush situations.  It does not perform well fighting alone.
.
Combat has proven that it is possible to dissable or destroy another battlemech 
with one well placed shot.  But this is rare. Even the lightest battlemechs 
manage to keep fighting or escape.  The AC-20 can do a lot of damage, but it is 
not the one shot solution the the Jawbreaker's sales materials suggest.
