soldier-rocketjump. access areas out of normal range through using the force of a rocket! / bomb squaddie. your shotgun and shovel can destroy enemy stickybombs!
demoman-stickyjump. a more HP costly but powerful version of the rocketjump. / ITS A TRAP! stickybombs are manually detonated.
soldiers can eventually get the direct hit (more powerful rocket launcher) and the buff banner (charge by killing enemies. at maximum charge you get minicrits!) and the equaliser (move speed and damage increase while your HP decreases).
demomen can eventually get the chargin targe (a powerful explosion-proof shield that lets you charge very fast for a short distance) and the scottish resistance (a heavily upgraded stickybomb launcher) and the eyelander (a dangerous and deadly sword that makes you stronger every time you kill!).
soldiers have 200 HP and move slowly.
demomen have 175 HP and move at normal speed.
charging demomen cannot turn corners but do move at about 750 hammer-units per second.
