The UPA heavy walker was developed late in the 35th century to help counteract the fact that many empires made fun of the grand and noble UPA for having no excessivly heavy weapons in its ranks.
2 medium repeater lasers
4 small laser guns
the 'bulldog' boasts capital ship class weaponry mounted on its heavily armour plated gun mounts. The turbo laser packs enough punch to rip open tanks in one shot and the autocannon is a generally effective cannon.
the medium repeater laser are used mainly for anti-infantry suppresion and the small laser dont do much . they were just added cos there was room. they pack about as much punch as an aerosol can being sprayed at you from 100 meters away .
but if used in a constant beam they can act quite effectivly as headlights to see where your going.
I built this mech because there appeared to be only thin weak walkers in my army. its sort of the opposite in terms of bulkyness
