I am giving the tabletop 3rd Ed. LOS Skirmish rules a go. Scenario is the machines are attacking a UNE refuling stop. The machines have an External Security Horde along with a Infiltration Horde and one G1C Nightmare. The UNE has a Commando Section with a Recon squad (Sgt commanding) and a Heavy Behemoth Platform defending. Both sides enter from their long board edge. The Rock formations on the board are rough terrain (1/2 movement allowance to move through and provides a +2 to hit modifier). There are the rock hills on the right side of the picture that is level 3 high. The hedgerows are level 1 line of sight obstacles. Level 1 is the height of a UNE commando/ G1 Nightmare. The posted pic is of the end of turn 1 (forces entered the board).
