The Crab has been a welcome addition to the regiments 
of the Draconis Combine ever since Comstar began 
supplying them in 3030. Since that date the Crab has 
earned a distinguished fighting record.

In 3045 the Draconis Combine made the Crab one of its 
standard designs when they decommisioned line used 
for the ageing TBT-7K Trebuchet. The line would have 
been used as another Dragon manufacutrer but the old 
machinery was limited to a maximum of 50 tons.

After that date the Crab has been produced in great 
numbers to become the Combines most numerous 
medium weight battlemech. Because the Draconis 
manufacturing plants could not replicate the advanced 
Ferro-Fibrous armor of the original design some minor 
modifications were needed.

The new design labeled the CRB-28 had 10 tons of armor 
and mounted one less heat sink than the original. This 
variant became widely used throughout the Combine and 
was greatly respected by pilots and foes alike.

Battle History

The CRB-28 has been widely accepted mainly because 
the original version had such a distinguished fighting 
history. While not quite as well armoured or heat efficient 
as the original, the CRB-28 has never the less continued 
to advance the proud record of the Crab. With the CRB-28 
seeing action in many minor skirmishes, the designers 
are impressed with the designs performance.
