Grenade jump

Much like rockets, stickies, and other explosives, a Demomans Grenade Launcher can be used to jump. The explosion has power and damage comparable to a rocket jump, but is far more difficult to time and execute. They are rarely used in actual play, but are a niche for Demomen wielding the Chargin Targe, Splendid Screen or Tide Turner, which can also give a boost while jumping and is similar to rampsliding. This form of jumping may also be preferable if you have stickies already placed and do not wish to detonate them to jump somewhere.
