How they would work and how would you use them?

(Green Bar represents Mech Height)(Red Bar Represents Weapon Height)
=(Raise Arms)=
Raise a Mechs Arms, Decreasing Speed by Half for Stability,
the -50% Speed Penalty i feel would help balance having Higher Weapons,
stopping everyone from fighting with their arm up 100% of the time,
=(Crouching)=
Lowers Mech Profile reduces Radar Signature by half, Decreases Speed to Half,
the -50% Speed Penalty i feel would help balance the new 400m Detection Radius,
stopping everyone from fighting Crouched 100% of the time,
=(Both)=
having both active would reduce your speed to 25%,
this is to balance Crouching with arms up,
