Modular wall block, interlocking block assembly, and retaining wall constructed of an assembly of modular wall blocks
A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall.

5. The interlocking block assembly according to claim 4 , and comprising a removable wall insert positioned within the vertical side grooves of adjacent like face blocks, whereby the wall insert creates a substantially closed-off fill cavity between the adjacent face blocks.
6. The interlocking block assembly according to claim 5 , wherein said wall insert defines a plurality of spaced apart vertical drainage cuts extending from an edge of said insert.
7. The interlocking block assembly according to claim 3 , wherein said first and second rear T-shaped formations of said embedment block further define opposing vertical side grooves.
8. The interlocking block assembly according to claim 7 , and comprising a removable wall insert positioned within the vertical side grooves of adjacent like embedment blocks, whereby the wall insert creates a substantially closed-off fill cavity between the adjacent embedment blocks and adjacent face blocks.
9. The interlocking block assembly according to claim 8 , wherein said wall insert defines a plurality of spaced apart vertical drainage cuts extending from an edge of said insert.
10. The interlocking block assembly according to claim 3 , wherein said face block comprises a shear lug projecting from one of the planar stacking surfaces of said block body.
11. The interlocking block assembly according to claim 10 , wherein said face block comprises a block-locating jut formed with at least one of the opposing sides of said block body, and projecting from the side towards one of the planar stacking surfaces.
12. The interlocking block assembly according to claim 11 , wherein said block-locating jut defines a base surface substantially coplanar with the stacking surface of said block body, and a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.
13. The interlocking block assembly according to claim 12 , wherein said block-locating jut projects from the side of said block body at a point intermediate the top and bottom towards the planar stacking surface.
