Plot
In AD 2170, there is only one force, that is the AEU(Alliance of Earth Union). No individual countries, it's peace, other than the fact that well, organizations that want to change the current world, exists. To fortify defenses, Mobile Armoured Weapons are made. Usually in the forms of customizable mecha units, they're versatile. Resource wider by utilizing outer-earth materials, they're not hard to mass produce at all. This doesn't change the organizations' nature, however, as it's still the same when it's in the tank-fighter-infantry weapons era. Unoffically a war, the AEU is trying to simply neverending retalitate against attacks, while finding a way to remove the attackers.

(... Just because I'm on the ground doesn't negate my weight... If I can't jump due to my weight then I shouldn't be able to move much faster then walking speed at all times.)
(3 is nowhere much. Dash proppels you forward with thrusters on your back and on the legs, and doesn't need to deal that much with gravity because it's been on the ground since day 1. Jump doesn't have thrusters, and gravity)
(It could be considered More difficult to push due to the friction against the surface that the object is on, but it really depends on angles and what direction the boosters are facing.)
