that reminds me of one of my friends (non canon) drones, it was a small vehicle with 0.5, or 1ton machine gun ammo "cased" (sort of) to blow out the front instead of the rear, and its primary attack was to charge (ram) and then the damage usually (almost always) set off the ammo.
Years ago, here in the DC area we had a pretty great grinder game in which people created a mini-grinder folder with 12 record sheets in it (three of each weight class). Trick was, you made the folder for SOMEONE ELSE- and therefore you were supposed to fill it with the kind of stuff you'd want your enemy to use against you. Cossacks, Jagermechs, Chargers, etc. (The big reveal for the players when they arrived was that actually the folder you made... was yours. ;) )
Anyway, Paul (yes, THAT Paul) got special permission to design his own Mechs for his own folder, and while he could have made decent if flawed machines... he really went all out to make bad Mechs. 'Server Room' sticks in my mind, with its eight C3 Master computers. They were unusable, wretched, designed to simply be funny as hell.
Well, one of them (I don't recall the name) was a kamikaze. A single MG (mounted in the head, backwards), fed by four tons of MG ammo, all in the legs... and MASC. The idea was to run up in someone's face, take a leg crit from the MASC roll, blow an ammo bin, and then have an engine detonation (we used slightly modded engine explosion rules to make them more powerful and a bit easier to cause)- taking out anyone nearby.
Paul ran up to my Akuma, got his MASC failure, and... an actuator and a hip. Rather than going out in a blaze of glory, he simply ran up and... fell down. Then got stomped on by the Akuma. So close to glory! I still wish he'd have been able to light that one off, that's something you don't get to see every day.
