Perhaps Attacking weapons: Lowest I use is Chavez Garrotte ; best in stockpile is Golden AK47 or Information kit [both 31] which have $450,000 and $1,000,000 upkeeps respectively. Free weapons win this round. 1:0 Defending weapons: I'm using 315 weapons lower than the stockipile weapon with the maximum defense  1:1 Attacking armour: Lowest I'm using is tactical armour ; can't do any better than that from the stockipile 2:1 Defending armour: Tactical armour is 15, Exoskelton is , so I could replace all 255 tactical armours for an extra point on each 2:2 Attacking vehicles: I'm using 319 vehicles below the maximum available stockpile item [Stretched Bentley, 24] 2:3 Defending vehicles: I'm using 109 vehicles below the maximum available available stockpile item [Nissan Skyline, 25] 2:4 Unless I've missed something somewhere? Looks like I'm neglecting defense. But I knew that anyway, haven't really added any skill points there since... since the start really. Edit: Just bought 388 Stretched Bentleys, so can't be attacking any better now. Total Upkeep: $63,330,000 If I were to max everything out in improving defending for all three, it would increase my upkeep by (30,975,000 + 25,700,000 + 80,400,000) = $137,075,000, taking it to around $200,000,000 Just not sure if it's worth it yet?
