FRAGS / C-4 / BREACHING/ SMOKE / FLASHBANGS
FRAGMENTATION GRENADES-
If there is one part of the game that can change what you learn, see, hear, or ever have thought to have worked before to win......its the frag grenade.  This is the easiest item to kill with, and the hardest to master.  No other weapon in Rogue Spear can assemble the versatility of it as well as the potential of both victory, or death.  The Frag is relitively simple to use, but its deployment is where players may faulter when trying to achieve success in battle.  It can bounce off of walls, go through window, go over buildings.   The only limitation for a frag is the user.  If you think of it, you can do it.  But, be warned......the slightest slip or misscalculation will only result in disaster. 
With the frag, there are 4 ways you can use it.  Also, a number of others, which are only limited by the players ability and imagination. But the 4 main ways have to be conisdered.

1.  Regular Use:   You select it, then aim, then throw.  Sounds easy...but it takes almost 3-5 seconds to do and allows the enemy to react.  So use it when they DONT expect you coming.  Also, it will bounce off of everything.  Walls, buildings, and even your own players...... clear your throwing arc or area before releasing it.  Its ideal if you are leading a rush with two people covering.  You close in on your objective....allowing your teamates to kill any counter attack.  Then release it. 

2.  Peaking Frag:  This is difficult to do because of the slight change of your reticle before it is thrown.  Look for yourselfs.  Peak around a corner and throw a frag.  Right before its released...your reticle will jump or move back torwards the object your peaking around.  Most often this will end up having a frag bounce back in your area and TK-ing yourself and your teamates.  The way to correct this is to lead it more away from the edge of the corner of the object your peaking around.

3.  Crouched Frag:  When you are crouched...your frag will only travel or go half the regular distance.  For example...if you threw one to the bunker the first time standing...if you try again crouched down...it will only go half way.  In open areas...this method isnt very good.  But when behind objects you can sit behind them.....let the frag-meter go all the way...and aim over the top of it. The result will be it dropping over the top....killing anyone sneaking up on while protecting you from the blast as well.

4.  Drop-Frag or Double Tap:  This is the most skilled use of the item.  Its simple to do, but relies on your timing.  Example is, say your rushing an opponent on snow base.  You start on the top or ledge while they are in the loading dock.  You rush down the stairs, with the frag selected but not charged for thowing.  You go though the door at the bottom but as soon as it opens you double tap the frag or drop it while running out in the lower area.  You dont stop running at all, and the frag ends at the doorway, for any enemy rushing up to the ledge, dieing in a heap of confusion while you continue your rush torwards the side of the dock.  By the time you get into the actual loading dock through the side entrances....the grenade goes off, killing any of the enemy rushing up to your start point.  This is just one of the million ways to do this style of fragging.  All it is, is that you are running forwards or backwards.....select the frag......double tap it to drop it at your feet......but continue to run so when it goes off....it wont hurt you but instead killing any foe that may be following you.
C-4
Trying to get that sniper...or elusive player and BAAAM!  The game is over and people are laughing.  You probably just got nailed by Flash [GoD] or by another fan of the explosive potenial of C-4.  This item is great to cover areas if you are playing with a lower number of players and have a lot of ground to cover.  Like the jungle map.  There are a lot of routes to take and defend.  C-4 can be used like a mine to cover the area.  The biggest thing about C-4 is how you will determine to detonate it.  To use it...you select it......place the charge...then back away.  Now, do detonate it just reselect it and hit your fire key and BAAAM.  But back to the detection part.  How will you know the enemy is coming?  SA HBS Sensors are ideal for this.  you place is away from the blast area.....then place your charge.  Then move back to your position.  If you have a enemy trying to flank you while covering another area.....you'll see it on your map display wiht your sensor.  Then all you need to do is select up your C-4 and kill him.  The concept is simple, but relies on a player to be able to use the map in the lower area of your status screen in the game.  Campers will also use C-4 to protect from fraggs.  But the easy way to defeat this is to use a frag to clear the area.  Frags will clear breach charges, mines, and C-4  when used. 
BREACHING / SMOKE / FLASHBANGS-
In the game you may have a host with certain kit restrictions on.  That will still leave you with items, if deployed right, that will devastate your opponent.  The Breaching Charge is a fun way to do something new, and get peoples attention.  Its great if you are in a room with a SA HBS sensor down.  Just select it and place it on the door where the enemy will be coming.  Then move back into a corner and wait for the sorry bastard to knock.  When he opens the door detonate it.  The breach isnt designed to kill, BUT WILL KILL if a player is next to it [ like opening a door that has it on the other side].  The screenshot below shows a tango doing a flip from it...and yes...hes dead.  So, if your in a closed area.....grab a breach charge.  Its advantage is the opponent cant see it like a mine or C-4 due to it being on your side of the door. 

Smoke and Flashbangs are other stuff that can help you in the game.  Flashbangs can give the Rusher that split second that will decide between living or dieing.  Ideal when the Reticle knock is on.  Smoke is good for maps that already have weather conditions, and large open areas.  All kit items are only limited to the use of the players imaginations.........so if the game is getting dull.  Grab one of these items and you might be the talk of the game if done corrcectly as well as get the ever honorable comment of ....    "  GG SCOUT, or WELL DONE FLASH, or even.....FLASH......YOU AND YOUR DAM C-4!"  for those comments are what we live for at times.
