Most of the time though, GURPS requires you to pay for any potentially useful effects. Some forms of battle aura seem to disintegrate the local environment, which would probably require high levels of Corrosive Attack, and which could be useful for destroying random obstacles.

For example, a character could have Corrosive Attack 10d (Area Effect 1, 2 yards, +50%; Emanation, -20%; Selective Area, +20%) [150]. Every turn, the character can deal an average of 35 points of corrosive damage to anything they desire within the area of effect (disintegrating clothing, destroying small objects, damaging large objects, etc.). With sufficient time (~10 minutes), they can even melt through the front armor of a main battle tank, though they will usually find easier way to disable/destroy such targets.
