Arsenal for you to customize your loadout (guns, uniforms, ammo, food & water), interact with this my middle mouse button (MMB)
There is also a map board near by so you can teleport between HQs (ACAV, Green Hornets, Spike Force, Mike Force)

Locate and destroy enemy AA, Artilery, HQ base on intel on the map of their whereabout.
Then defend the AO from enemy counter attacks/ FOB attacks. You captured the AO if it turns green.

* AO *
Ask Green Hornet pilots to fly you to AO, or just be copilot of a Huey and take your team there.
Use the map and mark for Airstrike and Mortar (if you can assemble mortar).
You can select colors/symbols for your mark, left click to place mark, remember to set visible to SIDE Visible.
Ask ACAV to build FOB for you to spawn near AO.

Even tho everyone can build basic structures, in Non-Acav section when you press N.
If you are ACAV, you can build every available structure and set up Forward Operation Base [FOB].
If you are ACAV, you can also drive Tanks and Trucks available at ACAV FOB.

To join ACAV, use the Map Board near Duty Officer then teleport to ACAV FOB.
To switch to ACAV, stand near Duty Officer, press H then click on the Tiger Emblem (Mike Force emblem) then choose ACAV (horse emblem).
To be able to build everything, stand near Duty Officer, press 6 to interact and select Engineer role (Wrench symbol).
Press N to see what available and to build by holding space bar.
Right/Left click to change between building Placement, Rotation, Height before you hold Spacebar to build.

* FOB *
You need Situtation Room (in HQ section) and Checkpoint (in Respawn section) as the core of your FOB.
Your FOB will decay after time, you need to give it Building Supply for it to last, the more you build the more supply it uses.
After building those 2 structures, you need to ask pilots to fly Building Supply (large or medium crate) to you.
Then pick up the building supply and place them near Situation Room, interact with Situation Room by pressing 6 and load crate, now your FOB is active.
You can spawn and get sandbag from Supply Officer (this guy is always near by Duty Officer, check your map to locate him, he's a copilot in some cases)
You can load sandbag to Situation Room like crate, but sandbags will not last as long as crates.

If possible, use the prebuilt FOBs on the map then just build Situation Room, Checkpoint, and additional structures if needed.
This help you save Building Supply and time. Remember to mark your FOB and also designate an area for heli to land.

If you are Green Hornets, you can fly aircrafts and only you can repair/refuel/rearm them at Airbase.

To join Green Hornets, use the Map Board near Duty Officer then teleport to GreenHornets FOB.

Fly Huey and OH-6 Loach to provide transport for ground troop and assist engineers with supplies.
Get supply from the Supply Officer, he's close by the Duty Officer at Pleiku Airbase. Then press 6 to interact and spawn the desired supply.
Fly close to the supply drop using auto hover (press X) and try to hook it to your chopper (press B) using rope.
