In a test I did I fired a single SSRM-2 launcher at a COM-1B in the Training Grounds. I was 48m directly in front of the 1B and aimed for the CT:
1st shot takes it down to 84% which means those two SSRMs did 36 damage.
2nd shot takes it down to 69% and strips both side torsos of armour. Damage done: 33.
3rd shot takes it down to 53% and strips the CT and LA. Again, 36 damage.
4th shot kills the 1B.
That's six SRMs, supposed to do 15 damage, doing 105 damage - or seven times as much as they should.
Edit: Now the bug has been confirmed on Live as well: Video by Wardenwolf.
