New class: Support - Has rocket launchers and a portable shield gadget that can deploy a waist-high shield anywhere on the ground. Provides immediate cover that can withstand 3 magazines of enemy bullets or 2 grenade blasts before disappearing. Shield can also be used to seal windows and doorways. Limit 2-3 deploys at a time for each Support player. Provides more dynamic options for offense & defense. Engineer - Instead of rocket launchers, let the Engineer deploy a sentry gun that automatically targets & shoots enemies, can be repaired, and can run out of bullets. The Assault’s ammo packs can restock bullets, but the Engineer cannot. Sentry guns should target infantry and light vehicles only within 75 yards. Provides additional defensive strategies and teamwork synergy. Gives defending teams more resilience in the face of enemy vehicles.
