General

 * Johnson's primary firepower lies at Mechs, use it wisely. Mech Overcharge can make all of your Mechs invulnerable for any attacks including leader power attacks for several seconds.
 * The con side is you may need to build more supplies than generators. That is to keep your mech supplied.
 * You may also need to bring more Nightingales than other leaders to keep themselves healed albeit you can utilize Combat Salvage leader power for your advantage.
 * Johnson's Leader Power Digging in Deep is the best UNSC Leader Power as you can divert all of your resources to the unit production and upgrades.
 * Generators that normally can siphon your supplies due to the increased price of 300 supplies for each construction will also become free to build.
 * Bunker is suitable for early defensive games or when you are still building up your forces.

Allies

 * Drop bunkers around your allies for additional defenses if they have infantry available. That will help them in holding their ground for a while.
 * Players can "Invest" their resources on Johnson, as he will be one of the most earning leaders after acquiring Digging in Deep which allows him to return the "Investment" back to the players that lend their supplies and power to you.

Enemies

 * Some players may be creative as they can use Bunker Drop to lay siege on your base. It's best to make a quick interception or deploy any anti-building units to destroy it.
 * Be wary of EMP MAC as it can immobilize your mechanical unit and allow them to be exposed to any attack.
 * Don't use any offensive leader power if the enemy's main force is a Mech and using Mech Overcharge Leader Power, as the entire mech will be invulnerable during the duration.
 * Isabel's Ghost In The Machine is practically your best friend. Hijack it as soon as the enemy were clustered for damage advantage.
