While these options CAN be used at any time during battle, the BEST time to use the top 3 options is during the phase where you can place units BEFORE you click the LAUNCH BATTLE button, which will help ensure that the AI doesn't get the same advantages. Toggle them on and then place as many units as you like, and then toggle it back off.
Numpad 1: Unlimited Requisition - toggle off when not needed. Best used BEFORE you start the battle. While this is on, each unit you place will GIVE you more points to spend. Toggle back off when you have plenty. The points will be there when you start the battle.
Numpad 2: Unlimited Units- toggle off when not needed. Best used BEFORE you start the battle. While this is on, each unit you place will modify the amount of units you can place for that unit type, HOWEVER once the units are placed on the map, you can place more units of that type. You basically have an endless supply of units.
Numpad 3: Unlock All Phases- toggle off when not needed. Best used BEFORE you start the battle. While this is on, the Phases for B and C or any other phases will unlock and those units can be placed. Toggle back OFF when not needed.
Numpad 4: Pause Score - toggle this on and neither team will gain points, which can prolong the battles.
Numpad 5: Pause Clock - toggle this on and the match timer will pause, prolonging the battles.
