Which of the statements accurately describe the role of a Live, Virtual and Constructive (LVC) simulation capability in conducting autonomous system T&E? (Select the two that apply)

1. A distributed LVC test capability will support productive experimentation even when human team members or the prototype hardware and software are not available

2. The Joint mission environment test capability enables suitable testing of all possible LVC combinations that include autonomous systems

3. The efficient and economic prototyping and experimentation efforts required for the development of autonomous systems depend upon a robust LVC distributed test capability

4. While vital to the development of human-machine team CONOPS, a distributed LVC test capability is of little use in testing interoperability and system of system performance
