The Mann-Conomy Update was a major content patch for Team Fortress 2, and was released on September 30, 2010, the update added 65 new items, including community-contributed content which contained the Black Box, Battalion's Backup and Grenadier's Softcap when those three items are used at the same time it creates the The Tank Buster set for Soldier.

The Black box - If you're lucky enough to sport the upper body strength to actually carry this monster, you can guarantee, after firing this half-a-ton hellraiser, it will be the only thing left thats not a smouldering pile of ash.

Grenadier's Softcap- Do you have a deep concerning invincibility complex? Are you crying for a fashion statement that just screams "Oh please shoot me!"? Then just before you go out to get yourself plugged full of lead, make sure that you are sporting the Grenadier's Softcap! I mean hey, you gotta die sometime right

The Battalion's Back-up - Now don't get me wrong, YOU don't need back-up but please dig deep in that war torn black pea of a heart and feel pity for the rest of your good-for-nothing team. All you need is the Battalion's Back-up to give them a helping hand. Just make sure you ain't too busy kicking somebody's ass when they call.
