1. First thing New class Heavy grenadier.
I think this class will be available for USA, China, MEC and Great Britain.
ID for class weapons.
a)The MGL (Multiple Grenade Launcher) is a lightweight 40 mm semi-automatic, 6-shot grenade launcher.
The MGL is multiple-shot weapon, intended to significantly increase a small squad's firepower when compared to traditional single-shot grenade launchers like the M203. The MGL is designed to be simple, rugged and reliable. It uses the well-proven revolver principle to achieve a high rate of accurate fire which can be rapidly brought to bear on a target. A variety of rounds such as HE, HEAT, anti-riot baton, irritant or pyrotechnic can be loaded and fired at a rate of one per second; the cylinder can be loaded or unloaded rapidly to maintain a high rate of fire. Although intended primarily for offensive/defensive use with high-explosive rounds, with appropriate ammunition the launcher is suitable for anti-riot and other security operations.
b)Same weapons as Rifleman but without optics.


2. New class RTO (Radio Telephone Operator)
Bag pack with army radio. This class is very useful in everything, defending, attacking, ambushing. This class only works if there is near Commander of Squad leader, commander and squad leader can give artillery support, and commander can give orders.
ID for class weapons.
Rifleman weapons but the M16A4 is with optics.
And RTO have Colored smoke.



3. New stuff for Combat engineer.
Mortar engineer can build it if there is one supply crate next to him.
And there is new class mortar gunner, to fire heavy mortar need two peoples(heavy mortar M120 120 mm), gunner and reloaded, but to fire light mortar one people(light mortar M224.)
a)M224 Mortar
The M224 system is composed of the M225 Cannon (14.4 lb), M170 Bipod (15.2 lb), M7 Baseplate (14.4 lb), and the M64A1 Sight Unit (2.5 lb). The mount consists of a bipod and a base plate which is provided with screw type elevating and traversing mechanisms to elevate/traverse the mortar. The M64A1 sight unit is attached to the bipod mount. This smooth bore system can be gravity-fired or fired by using a manual spring-loaded firing system.
The M224 Mortar can fire the following principal classifications of training and service ammunition.
1. High explosive (HE)--Designations M888, M720, and M720A1; Used against personnel and light material targets.
2. White phosphorus (WP)--Designation M722; Used as a screening, signaling, casualty-producing, or incendiary agent.
3. Illumination (ILLUM)--Used in night missions requiring illumination for assistance in observation.
4. Training practice (TP)--Used for training in limited areas. These rounds are obsolete and not used anymore.
5. Infrared Illumination (IR)--Produces illumination which is only visible through the use of night vision devices.
6. Dummy-- this round is used for practice or clearing misfires

b)M120 120 mm Mortar.
The M120 fires fin-stabilized ammunition from a smooth bore. Unlike its smaller ammunition cousins, the 81 mm and 60 mm mortars, the fin blades of the ammunition fired from the M120 are not canted. Thus, no spin is imparted to the projectile in flight. Although heavy mortars require trucks or tracked mortar carriers to move them, they are still much lighter than field artillery pieces. They outrange light and medium mortars, and their explosive power is much greater.
The M120 is transported on the M1100 Trailer by the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV).
Specifications.
Maximum Range: 7,240 m (7,917 yds)
Minimum Range: 200 m (218 yds)
Weight: 144.7 kg (318.5 lbs) weapon set up without ammunition (326.1 kg (717.5 lbs) mounted on trailer)
Rate of Fire: 16 rounds/min first minute, 4 rounds/min sustained
Crew: 5
The M120 Mortar System consists of the following major components:
* M298 Cannon Assembly (110 lb)
* M190 Bipod Assembly (70 lb)
* M9 Baseplate (136 lb)
* M1100 Trailer (399 lb)
* M67 Sight Unit (2.5 lb)
The M120 is capable of firing the following munitions:
* M934 High Explosive Round
* M934A1 High Explosive Round
* M933 High Explosive Round
* M929 Smoke Round
* XM930 Illumination Round
* XM930E1 Illumination Round
* XM983 Illumination Round
* XM931 Practice Round
4. Mk 47 Striker
Next the best thing what can make Combat engineer, but there need to bee two crates of supply. This monster gun operate mortar gunner class and it need two peoples.
In addition to being able to fire traditional grenades like the Mk 19 grenade launcher, it can fire smart grenades that can be programmed to air burst after a set distance. A computerized sight allows the user to set this distance.
The model is currently being evaluated by the United States armed forces and the Israeli Defense Forces. It is currently in combat use by some US Special Operations forces in Afghanistan.
And there can be new HMMWV with Mk 47 Striker

I hope my ideas will be useful.
P.S. Sorry for grammar
