Communication and Marking

Communication is top priority whether you're a rifleman or a platoon leader. Remember, during a session, if you're not shooting or moving, you should be communicating.

Radio Communication

Through our radio system (ACRE2), we use a full-duplex system which allows multiple people with different radios to talk on the same channel at the same time. This means we have to practice certain protocols to ensure information flows up and down the chain of command properly. By default the Caps Lock key allows you to transmit over the radio. Below is an image of the message that will appear in the bottom right of your screen when you are transmitting over the radio.

In addition to letting you know that you are transmitting this message also display some useful information. It shows which radio you are broadcasting on (in this case the PRC-343) and which channel you are broadcasting on (in this case Block 1 - Channel 1). This is important to note so you are transmitting on the correct channel using the correct radio. Before the mission starts it is worth checking your gear to see which radios you have. If you have to change the channel you are broadcasting on, you can open and close the currently selected radio by using the hotkey Ctrl + Alt + Caps Lock Or by double clicking the radio in your inventory. If you need to cycle between multiple radio, use the hotkey Ctrl + Shift + Caps Lock. A full list of hotkeys can be found in the section below or the mission briefing.

Radios & Radio Channels

All radio nets are listed at the map briefing screen. However, you can also find a list of them here. All fireteams have their own private AN/PRC-343 ("walkie-talkie") while communication between assets, squads, and the platoon all happen on different long-range radios such as the AN/PRC-152, AN/PRC-148, and the AN/PRC-117F.

Short-Range AN/PRC-343:

The AN/PRC-343 or 343 is most basic radio we use. It is mostly used for communication between Fireteam leaders. Almost every position uses a 343 to communicate and it is an important radio to become familiar with. The 343 has the shortest range of all the radios we use so it is important to remember it can only be used to contact nearby elements. The 343 comes equipped with a 2.5in antenna, a max output of 50mW and a range of up to 500 metres in rural terrain. The 343 operates on an Ultra High Frequency. This means they cannot transmit or receive messages from a 152 or 148. Below is an image of the 343 when you open it up.

Looking at the 343, you can see there are two dials at the top as well as a detachable handle on the left side. The left dial can be used to change the volume of your radio. The right dial can be used to change the channel of your radio. The radio will go from channel 1 to channel 16. The handle on the right can also be detached to in order to change the block being transmitted on. Currently there is not need to change the block. Make sure the handle is attached or the radio will not work.

AN/PRC-148

The AN/PRC-148, a more advanced radio is generally used by a squad leader and specialty (ex: engineering) leader to communicate with command. The 148 uses pre-programmed channels like the 343 but with a much longer range. It has the same specifications as the 152.

Use the default key to open up your 148 and you are left with that screen. To change channels, once again you have to press the top middle button. To change volume, simply click the button on the leftmost side.

AN/PRC-152

152s are currently not directly issued in the framework, though may be found mounted in some vehicle racks

The AN/PRC-152 handled by the squad leader to communicate with command. It uses predefined, pre-programmed channels like the 343 and 148, but is much more powerful than the 343. It functions on a Ultra High Frequency, has an output of 5W, and a range of up to ten kilometres in ideal conditions.

The 152 has two controllabe buttons that you need to worry about: the top middle one, which changes channels, and the buttons at the side which are used to adjust volume. To change a channel, simply click on the top middle button (left to go up a channel, right to go back one). To change volume, you do the same.

Radio Procedures & Prowords

Before making a transmission, remember the following:
Accuracy: Is what you're saying solid information? When reporting contact, ensure that you have double checked the direction and distance of the contact.
Brevity: KISS - Keep It Short and Simple, or Keep It Simple Stupid. Convey as much information as necessary in as few words as possible.
Clarity: Make sure that you speak slowly, steadily and as clearly as you can. Do your best to remain calm under pressure.

An example:

Scenario: You are Alpha 1 Fireteam Leader and you see enemies in front of your team, but they're not aware of your presence.

Rather than a message such as:

Alpha Squad Lead, this is Alpha 1, we uh, see about a squad size or even maybe two squads of infantry in the open over here and we need to know if we should shoot them or wait. So far, I don't think they uh, have noticed us and we're prone on the hill here.

A proper message with brevity would be:

ASL, this is A1, we have an EI squad soft contact 300 meters from us at the treeline north. Check map for "EI" mark.

Some good key words to remember are listed in the table below. Use them to limit the time you're on net.

Proword	Meaning
CORRECTION	An error has been made in this transmission. Transmission will continue with the last word correctly transmitted.
I SAY AGAIN	I am repeating transmission or portion indicated.
OUT	This is the end of my transmission to you and no answer is required or expected.
OVER	This is the end of my transmission to you and a response is necessary. Go ahead; transmit.
BREAK	I hereby indicate the separation of the text from other portions of the message.
ROGER	I have received your last transmission satisfactorily, and loud and clear.
SAY AGAIN	Repeat all of your last transmission.
SEND	I have received your initial call; pass on the rest of your message.
THIS IS	This transmission is from the station whose designator/callsign immediately follows.
WILCO	I have received your signal, understand it, and will comply. To be used only by the addressee. Since the meaning of ROGER is included in that of WILCO, the two prowords are never used together.

Direct Communication

Direct communication is any communication done between two or more players in real time. Direct communication is a skill that must be developed in order to relay information between fireteam members more efficiently and ultimately increase surviveability.

Acre2 Direct Speech

Besides Radio comms ACRE also supplies a direct chat system which can only be heard by those directly around you. This system allows you to choose your voice volume by holding tab and scrolling up or down with your mouse wheel. Based on your mission or surroundings your voice volume can be very important. Below will be an info sheet pulled from the ACRE2 wiki itself. By default your TS3 Push to talk or voice activation setting will be your direct speech.

Keep these in mind. The AI or players can and will react to you based on what they can hear. In most cases it is not necessary to go over 3/5 and I would recommend staying at 2/5 until you get into combat so you do not end up disrupting briefings or orders.

Contact Calls

A contact is anything unknown that you're able to visually or audibly identify as being present. A contact is not specifically an enemy vehicle or infantry, so make sure you always identify prior in order to avoid friendly fire incidents. Examples of contact calls:

I got audio on something tracked to the north in the treeline. Unknown distance

Contact, infantry moving in the trees to the southwest, 300 meters.

Marking

Marking is any visual form of identification across one or more mediums. This includes marks on the global map, spray painting doors after buildings have been cleared, or even lasing targets with a laser designator.

Map Types

There are two map types: Textured and Un-textured. The map type can be toggled at the top right of the map screen. It is recommended that you use un-textured for clarity of terrain and markings.

Textured

Un-Textured

Map Marking

There are two kinds of map marking: Icons and Drawn Lines. Every mark on the map must be color-coded based on who the mark is for. There are also specific techniques that platoon and squad leaders must use when developing plans.

Marking Color Code

When marking the map, it is important to use the correct color to indicate which element the mark being added is addressed to. This means that all red marks are for alpha squad and so on for each element. Below is a list of the color code used for each element.

Alpha - Red
Bravo - Blue
Charlie - Green
Individual Specialties (MMG, MTR, MAT) - Purple
Command - Yellow
Armor - Orange
Everyone - Black

Prior to mission start, you can set your marker color at the top right of the map screen. This should be done by everyone while safe start is on. Below is a image of the drop down to select your marker color.

Icons

Icons are used for specific points such as dismounting, convoy start points, or even mortar/air strike requests. Icon example:

Drawn Lines

Lines are used to draw movement plans, areas of operation, or even specific blocking orders. Lines can be drawn by holding down the left control key and left mouse button. Line example:

EI Map Marks

EI: Enemy Infantry

Every "EI call" must be marked on the map once they are pointed out. This allows for direct identification on all levels of command based on color-coded marks. As an example, if it's a green "ei" mark, then charlie has obviously spotted and called out enemy infantry. Alternatively, if it was blue, bravo has spotted them.

In this example, Alpha has marked spotted EI at the top of this hill:

In general, we also name terrain within the area of operation. As this hill's overall peak is 100 meters above sea-level, we'd often refer to this as hill 100 and mark it as such.

Command Map Planning

Regardless of who is in command at the time of mission start, all mission commanders need to follow the same type of planning system. This ensures that all players have a streamlined and structured experience without the need to adapt to different leadership styles as a whole. Failure to do so will result in commanding rights being revoked. The following are examples of full plans.

Convoy

Also note that ALL convoy planned-missions must have a Mount Order defined prior to mission start. A stand MO looks like this:

Infantry

Full Plans

Convoy with Infantry Dismount/Assault

Calls for Fire

Calls for fire will always be directed by a Joint Terminal Attack Controller(JTAC)/Forward Observer(FO) if available. If not, all leadership can request support through their chain of command. Only the highest level leader may contact the supports directly for fire if there is no JTAC/FO available.

Mortar Support Marking

Air Support Marking

For non-JTACs, mark the target on the map w/ a descriptor, and then communicate with higher elements to make a request for a strike on that target.

For JTACs, see JTAC-Aircraft Operations.
