Charles Kinkaid had his personal Hachetman modified to 
pack a bigger punch.  First, he ordered his techs to 
replace the original weapons with a single large bore 
autocannon.  Although the potential damage for the mech 
remains relatively equal to that of the original, the dmage is 
concentrated in one location, increasing the mech's 
effectiveness in combat.  With the removal of the two 
medium lasers, Kinkaid no longer had to worry about heat 
buildup, and so his mech drops a heat sink and adds more 
armor.
