Mines can be used to take out tanks and infantry the best way to use them against infantry is mainly running up to the enemy forward barracks and main with a jeep and then mining the entrances of the buildings. This will one kill there infantry and two damage there buildings and three create disturbances within there team. The prime building you should mine is there vehicle factory to kill infantry and tanks while they are trying to get vehicles onto the field if you manage to kill a tank it will put a small dent in there resources as well as preventing the enemy team from getting mobile it is best to rush there vehicle factory early game for the best effectiveness.

When placing mines to kill tanks i suggest you place the in a pile of 2/3 for light tanks and apcs - 4/5 for medium tanks - 7/8 for a heavy tank. When you do place your mines be sure not to move your mouse or player character so all the mines are in each other so it looks like one mine this will confuse newer players to thinking it is just one mine. Only to find it its actually afew.

Also one other tip with mines is the ability to detonate mines you do this by placing 8 mines in a pile then once you place the 9 mine the 8 mines you placed previously with explode this is good against heavy tanks using diffusal. Veteran players often refer to this as a 9 mine.

The mortar being one of the best weapons is very good against infantry and can kill in one hit if you hit them directly even with health upgrade. It is the early game siege weapon and it very good at clearing out enemy entrenchments like turrets and turrets. However is probably one of the hardiest weapons in empires to use therefor many people don't play grenadier i suspect because they don't feel confidant enough with the mortar against infantry which is fine it does take awhile to get the hang of it. You also must learn to lead your targets if the are moving at speed shoot where there going to be not where they are. If you are not sure what leading your target means i suggest you go and look it up on google.

The mortar is also very good against buildings. When up against vehicles i suggest you fire off your mortar first then switch to your RPG instantly to fire both weapons off quickly to get the maximum damage on the target.

When you come across an engineer building a turret i suggest you aim slightly behind and to the side so you hit him before he builds it.

The green crosshair rectile is for range finding to give you an idea of where you are going to hit.

NF mortar

The rpg is very good against enemy tanks when you are lead of a squad it is best to have 3 grenadiers in that squad so you can designate a single target with squad target so all the grenadiers fire at the same target thus killing the enemy vehicle quicker. A good squad utilizing walls and squad target's can easily hold off against mediums and maybe even heavy's especially now that grenadier upgrade has been added into the game.

The RPG can also be used to snipe engineers building turrets as they tend not to move while building there turret. Also i may add rpg's are not good vs buildings

The first skill should use as grenadier is speed upgrade. When i play grenadier on foot i mainly use speed upgrade, health upgrade, melee upgrade and ammo increase or defusal another i may use is accuracy upgrade to make the pistol somewhat better.

When driving a tank the first skill you should use is defusal then Armour upgrade then Armour detect. You can be very effective driving a tank as grenadier because of the Armour buff, mines having no effect and of course knowing where to hit to enemy Armour.

When playing grenadier movement is key never stop moving when you come up against another player jump around and strafe as much as possible making your harder to hit and kill.

The pistol1 (starting pistol) is one of the best weapons in the game its good on the move and does a good amount of damage and has a decent clip. You should be able to finish off there infantry with it once you hit them with the mortar.

The BE deagle isn't really that great, the nf shotty pistol got a unnecessary nerf so i don't really suggest it. The BE machine pistol however is great and really good at close range. But i really do suggest you stick with the pistol1 due to it being the best all round choice.

The grenadier class may be one of the best and most us full classes in the game however its the hardest to master the other best class being engineer. I think every player should practice grenadier as much as possible once they get good at engineer.

It takes 3 mortars/rpg's to kill a turret.
