Sledgehammer grips, strikes and ideas

Sledgehammer.

For breaking in. Demolition. And work.

Or at the spot, right away as a weapon, if needed.


-


Normal grip:

-One hand near the base and one next to it or quit close by.


Downwards

Angled downwards

Sideways

Angled sideways

Angled upwards


-


One hand gripped around the base and one hand gripped near the head of the hammer and angled downwards

One hand gripped around the base and one hand gripped near the head of the hammer and sideways forwards

One hand gripped around the base and one hand gripped near the head of the hammer and angled upwards


-


Battering ram


---------------------------------------------------------------------------------


More range of motion.


Certain movements.


-


Rotating the hammer each time

-Hit and rotate to neutral position again and hit again

 Fluid motions, and range of motion and some more speed and power right away


-


Full rotations with the hammer around the body and strike.


-


Hammer throw. 

-Rotations with the hammer and throw


Hammer throw.

-With making full rotations with the body and throw


Or forwards overhead throw (I still need to test this one).


Explanation: Can be used when to dangerous to stand close by. Then throwing the sledgehammer from a distance.


---------------------------------------------------------------------------------


Grip change.

-Other hand in the front

And stance change.

-Other leg forward for example


Can also be used to go on longer, if needed.


-


Close gripped, hands close to one another, around the base

-Harder strikes


Wide gripped

-Faster, but less hard strikes


---------------------------------------------------------------------------------


Battering ram. 

-Forwards

-Sideways

-Backwards

-Upwards

Wide gripped


-


Extra: Two hands gripped at the sledgehammer head and battering rams

Military shovel digging, shovelling

Military shovel digging, shovelling

Shovelling with the right hand on the front
Shovelling with the left hand on the front
-It's possible to change the front hand if needed, this can be usefull, when one arm gets tired.

Standing. Standing very squated. And kneeled.
And then digging deeper from inside the trench or squared hole itself.

And if the ground is to hard it's possible to put one foot on the shovel blade and to then push it into the ground.

-

And it's possible to dig with a broken off shovel blade if needed.
-Normal and it's possible to hold it reverse.
 And with only the left hand or the right hand. Switching when one hand or arm gets tired is possible.

-

And digging with the hands

Handgun cocking with tied hands

Handgun cocking with tied hands


Important: using dry fire rounds offcourse for trying this out and for training this.
-Warning: A finger or skin maybe, might get stuck by the ejection port
And it's more only for if really needed.
It's very dangerous with a real round, because a handgun can go off because of a fall,
though most modern handguns do have a safety and it's possible to accidentually
hit and pull the trigger with a finger.


1 You don't have to tie up the hands, just holding the hands and or wrists together
  in multiple ways is possible.
2 It might be useful to warm up the wrists a bit according to my experience.


It's possible to cock a handgun with tied hands by hooking the rear sight to 90 degree angled furniture.
90 degree angled walls.
And more.

It's possible to cock a handgun by trying things out with both hands and or wrists together.






And it's possible to cock a handgun by using the teeth, but it's dangerous for the teeth and I would not advice doing it unless really needed or maybe with some padding on the biting area just to try it out.

I all thought this up myself. So it's mostly experimental.

Firearms trainings and drills - Two handed and one handed shooting with assualt rifles and more

Two handed shooting.
-Right handed main grip and trigger pull
-Left handed main grip and trigger pull

One handed shooting. When wounded for example. (safety is very important)
-Right hand
-Left hand

It's possible to train all and can be of use. Though it can be most adviced to train mainly train your main way of shooting.
And changing it up sometimes while shooting a single magazine is possible.

With an assualt rifle, when you have a not to wide cover, you can shoot from both sides by changing up your grip, this can be useful or even
important for tactics.
-Putting it against the right shoulder with a right hand trigger pull for shooting from the right side
 and putting it against the left shoulder with a left hand trigger pull for shooting from the left side

Important:
-Right handed shooting: Right eye open and for aiming, left eye closed
-Left handed sooting  : Left eye open and for aiming, right eye closed
Being able to hold one eye open and one eye closed at both sides is a good skill.
-And you can train this for both eyes

Military combat training, hand to hand combat version 3

Military combat training, hand to hand combat. Version 3.
Theorethical and experimental
 Self made notes by me: J.K.

Warning: This is a military and mercenary training document.
Most of this manual is not meant for on the streets.
Extra warning: Some things should only be done when there is no other option, if you are captured
and you did something grewsome you might be screwed, so somethings are only meant for in life
and death situations.

Knocking out, destroying and or killing the enemy with the bare hands
fast and effectively is the idea.

Part 1: Knocking out, destroying and or even killing

Punching
 Hitting as hard and fast as possible. And fighting stance and defence are also important.
 There is normally no time to mess around.
 Punches: Straight, hook, uppercut
 Interesting areas to hit: Mandible, Temple, Throat. And also the liver and plexus.
  And hitting the nose hard enough can result in a broken nose
 Hitting the neck.
 But you can also just punch very hard and punch and punch and just knock him out.

Other attacks:
Elbows
 There are multiple elbow strikes.
 Elbows to the head
Knees
 Knee to the head for example, very hard, but you can also do them to the body and to the upperlegs

And kicks are also possible
 Front kick is fast and easiest
 Round kick
 And you can attack the knees and chin bones with kicks. This can also be done with side kicks.

Kicks 2: When an enemy is grounded you can kick his head
         Front kicks, round kicks, side kicks anything goes.
         -With a front or side kick, kick with the heel.

Clinch position
 Knees and elbows are very effective in the clinch but punches can also work (mainly sharp, short hooks). You can also use different kinds of elbows in the clinch.
 Throwing an enemy in to the air and dropping him as hard as possible on his neck or head and further attacking him.
 And in the clinch position you could deliver very hard blows to your enemies neck (AKA rabbit punches).
  Do this as hard as possible
 And if needed you can headbutt in the clinch, use the forehead to hit the enemies nose area.

2: Basicly ground wrestling only works 1 on 1, if there are 2 or more enemies you can't really
    wrestle, they will kick and punch you in the head, it's just not realistic.
    Though when already on the ground with multiple enemies you can use wrestling attacks. And experience is important.
    And standing wrestling and clinch position training can be very usefull, when fighting clinches happen often.

1 Defending, if there are multiple enemies and you're on the ground.
 I haven't tested this but when multiple enemies attack you, hold your hands correctly, rolling might work,
 And you can use your hands and or legs to make them fall. And you can exploit their joints, attacking
 for example the inside of the knee with a kick or a grab.
2 Getting up fast.

When one on one you could do:
Takedowns
 Extra: You can also pick up an enemy and drop him down as hard as possible on his neck or on the head
Chokes, locks and bars
 For chokes; Arm around the enemies neck and grab the other arms inside of the elbow and
 pull tight and you can push his head forward. Cut off his blood supply to the head.
  You can do standing chokes and chokes on the ground
 For locks and bars, use leverage on joints, put them in a direction they can't go to, pulling
 backwards or applying torsion. You can break joints hard and fast.
Attacking on the ground:
 Punches
 Elbows
 Palm strikes
 And hammer fists

One tip: You can break an enemys fingers. It's an ancient Greek olympic games technique.

And: Neck breaking (neck crank). Fast and effectively
      Can also be done after knocking the enemy out.


Update: Some styles.
Attack, attack hard and fast

Evade, untouchable and hard hits right time

Hit block hit block hit

Grab the enemy and punch, elbow and or knee him and or take him down and kick his head
-Elbows and knees are hard short range attacks and they work well.
Ground and pound. Takedown and then punches and or hammer fists.

Combining is possible

3 Other techniques
 Eye gouging
 -Finger jab to the eyes.
 -Spearing the eyes while on the ground or in a clinch.
 Ripping an ear off.
 Biting, as hard as possible (if really needed). Biting through flesh and bone. Maybe you could even break the radius or ulna with a hard enough bite force.
 Headbutt against the face, hit around the nose area
  Also works in the clinch
  There is a rule saying hard against soft for strikes works very effectively
 Knee to the neck
 -Kick enemy down by kicking into the inside of the knee (get behind him or while on his side must also be possible), while already holding his head and pulling his head and then the above
 Knee to the temple
 Hits to the kidneys
 Hits to the neck
 Hits to the spine
 Hit one ear or both ears with open hand(s)
 Stamping the head

-

For if an enemy or another enemy suddenly shows up from the side or from behind you:
Elbows
-Backwards. Spearing and round.
-To around a 45 degree angle to the side. Spearing and round.
Hammer fists
-Backwards.
-To around a 45 degree angle to the side.

------------------------------------------------------------------------------


------------------------------------------------------------------------------

Part 2 Training:
Important for training:
Realistic, Keep it realistic due to fighting training. And don't injure a fellow army member offcourse.

1:
Boxing
 Punching hard. and fast offcourse.
  And big swinging can be dangerous.
 You can train punches with boxing gloves or even better MMA gloves with another army member.
  MMA gloves are more realistic and give a more realistic idea.
 And you can train fast and hard punches on a punching bag with boxing or MMA gloves.
  And don't get injured. Boxing gloves can be better this time.

Tip: Watch boxing matches and trainings, watch heavy bag work.
        You can learn a lot from this.

Kikboxing
You can train kickboxing.
And watch kickboxing and muay thai matches.

Wrestling:
You can train wrestling.
You can watch wrestling matches, MMA submissions and escapes for when you get trapped.


MMA:
You can train MMA.
MMA consists out of striking and wrestling
And takedown and ground and pound

Here's a tip: Watch MMA fights.
 You can learn a lot from this


Military training: And very importantly: Sparring against 2-3 or more opponents.

More advanced reloading

Without firing shots, reloading only.

Reloading while looking at the gun and the magazine.
Blindfolded reloading.
Reloading while walking and looking at the gun and the magazine
Reloading while walking and only looking at the gun or not looking at the gun and the magazine
Reloading while running and while looking at the gun and the magazine.
Reloading while running  and only looking at the gun or not looking at the gun and the magazine.
Reloading while running very fast  and only looking at the gun or not looking at the gun and the magazine.

And also increase the reloading speed with each of the above.

By Jeffrey Koelewijn

Update: Doing speed reloads and tactical reloads like this.

Update: Reloading while kneeled. Reloading from cover. Reloading while laying on the ground.

Seeing further and hearing further with simple methods

See further by making a hole with the thumb and pointing finger and holding it right in front of one
eye while holding the other eye closed and seeing through that small hole made with the thumb and pointing finger.-With a camera this is called aperture (f value), the smaller the hole through which light shines,
 the sharper the image. But there is a slight downside, which is less light gets through to the sensor.
-And in real you will have a smaller viewing range.

Making shells with both of the hands and putting each hand behind an ear, with the hands outwards, forwards in around a 45 degree angle.-Experiment with this to hear sounds harder and better to a certain radius
 Note: You get more sound by a certain radius, so less radius but more sound, more focussed
          sort to speak

More shooting information and two drills

Trigger finger placement and problems:
-Too much to the left, gun will go right a bit
-Too much to the right, gun will go to the left a bit
Extra:
-Too high, gun will go up a bit
-Too low, gun might go up or down a bit, depending on certain factors.

Keeping sight alignment while moving around
-Moving from slow to very fast to running
-Walking forward, backwards, sideways, pivotting. And just random movement.

Left to right and right to left transition drills assualt rifle
 Sometimes needed from cover
 1 Switch from shoulder
 2 Complete regrip
So you're shooting from the right side from a cover and then you go to the other side and shoot.
