+## Homework 3: Example Simulation Recording using OpenDIS Network Streams
+
+<!-- Viewable at https://gitlab.nps.edu/Savage/NetworkedGraphicsMV3500/-/blob/master/assignments/src/MV3500Cohort2024JulySeptember/homework3/README.md -->
+
+### Assignment
+
+1. Adapt the functionality for [OpenDIS ExampleSimulationProgram](../../../../examples/src/OpenDis7Examples/ExampleSimulationProgram.java), modifying provided code
+2. Experiment with the enumeration values that set up each entity and PDU. What works for you? What makes sense for your future work?
+3. Adapt or replace the UML diagrams to describe what you have going on.
+4. Record, save and replay your result stream using [PduRecorder](https://savage.nps.edu/opendis7-java/javadoc/edu/nps/moves/dis7/utilities/stream/PduRecorder.html) or [Wireshark](https://www.wireshark.org)
+ * see local [assignments/src/pduLog](../../../pduLog) subdirectory for latest opendis log files
+ * Coming soon, we will also (again have) [X3D-Edit](https://savage.nps.edu/X3D-Edit) for DIS stream recording/replay
+5. Observe good-practice conventions in the [assignments README](../../../README.md) and [current-course README](../README.md) instructions.
+
+This assignment presents a Problem Prototyping opportunity.
+While some minimal functionality is expected, the general outline of
+a networking problem and proposed solution holds great interest.
+Think of it as warmup preparation for your future work.
+
+This is also a freeplay opportunity.
+You have the option to pick one or more of the provided course example programs
+and adapt the source to demonstrate a new client-server handshake protocol of interest.
+
+Be sure to provide a rationale that justifies why the networking choices you made
+(TCP/UDP, unicast/multicast, etc.) are the best for the problem you are addressing.
+
+You may find that the prior [homework2 README](../homework2/README.md) still provides
+helpful details on what specific deliverables are expected in each homework assignment.
+
+Team efforts are encouraged, though if you choose a team approach be sure to justify why.
+This is a good warmup prior to final projects. Have fun with Java networking!
+
+### Prior Assignment, August 2019
+
+In 2019, students worked together on a single project to check wireless multicast connectivity recently deployed on NPS campus.
+
+See their experimental results in the [NPS Multicast Connectivity Report](../../MV3500Cohort2019JulySeptember/homework3).

+/**
+ * The purpose of our code is to simulate a sea-based defense scenario where a ship
+ * tracks and attempts to shoot down an incoming enemy missile using an anti-air missile,
+ * with a 70% hit chance per shot. The simulation updates entity states and actions,
+ * which are communicated over the network using DIS PDUs, ensuring synchronized interaction
+ * between entities. The simulation continues iteratively, sending PDUs each loop until the
+ * enemy missile is either destroyed or the simulation ends.
