If you do end up deploying the Vickers where I suggested, then the other part of this suggested setup would be:
Task Organization:
Left Flank Force: 1 or more infantry units
Center Force: 1 or more infantry units
Reserve: 1 or more infantry units
Heavy Weapons: The Vickers MG
CP: Your leader
Deploy Heavy Weapons to the black house on the SE corner of the map, as I recommended.
This plan will use the left side of the map as a series of fallback defensive lines for your infantry.
Deploy Reserve + CP in the "H" shaped red-roofed building (right-center of the map).
1. First defensive line: Left Flank Force on N hedge border of the plowed field S of the number "16." Center Force in building with the walled garden. (This covers the open field where the number "16" is). Try to get some good shots on enemy in the open, then displace and fall back before return fire gets to enough to suppress you.
2. Second defensive line: Gradually refuse your left flank by displacing Left Flank Force to the S hedge border. Continue holding the building with the walled garden as long as possible, as this is the "hinge" of your position.
3. Third defensive line: As Left Flank Force continues to hold the building with the walled garden, refuse the left flank still further by pulling your Left Flank Force back from the S hedge of the plowed field to the wooden building on the SE corner of the field, and from there if necessary withdraw SE to the light trees hex (your 1st reserve location). The Vickers will be able to cover them at that point. In the meantime, continue holding the building with the walled garden as long as possible.
4. Once the left flank is safely refused, Center Force can concede the building with the walled garden and withdraw SE to the treeline.
