Final answer:
The maximum transport capacity of the BDU-33/MK 106 transport module is 20 tons, but after accounting for the battery, the actual maximum cargo load is 3 tons.
Step-by-step explanation:
The maximum transport capacity of the BDU-33/MK 106 transport module is 20 tons. However, in the given context, 85% of the cargo capacity is taken up by the battery, meaning 85% of the 20-ton capacity is used for the battery. So, the actual maximum cargo load after accounting for the battery would be 15% of 20 tons, which is 3 tons.
