Gentlemen,the Uziel.

More specificaly,the UZL-2S. It carries around a pair of Charged Particle Projection Cannons for long range conflict,a Crossbow SRM-6 rack for close quarters confrontations,a machinegun for reducing infantry to fertilizer,and jump jets that allow 180 meters of upward lift. And it has impressive waste-heat management systems!
To top it all off,it's fast at 97 kph,and well protected with eight tonnes of solid armour.
Fear it. Just try not to soil yourselves when two orbs of charged particulated death come screaming your way.
EDIT: Also,for when I feel like looking at a cute mech (why yes,they DO exist!),I look at the KiwiBot.

The one that looks like a bird. I so enjoy that mech,and its pilot isn't uninteresting,either.
