Ves had very high hopes for the sniper bunkers. They would offer fixed and highly secure positions for the Amaranto Mark III to attack her targets.
Being able to draw on the much larger and much more impressive power generators of the Torturous Scream should allow the ace marksman mech to charge her Instrument of Vengeance to full power a lot faster than if she relied on her own internal power generation.
The extensive surface contact with the enormous hull of the Torturous Scream should also allow the Amaranto Mark III to have virtually no concerns about heat buildup.
Unless the Amaranto was generating an astronomical amount of heat in a very small time frame, she should have no issue with dumping her excessive waste energy directly into the battleship. The Torturous Scream would be more than happy to serve as her gigantic heatsink!
