When using the laser as a tool to be extracted when in hostile territory, a powerful green laser beam is indispensable to spotting the troops who are to be picked up.

2. What type of laser design is the most practical?

So what is the most practical and useful laser design that can be used by someone on the ground, in the heat of combat? A design that is able to be mounted to a rifle will be very useful and provide a great advantage to whoever is using it. This means that a smaller design will be the most effective as some of the larger laser units are too bulky and can actually impede the sight of a soldier while also adding too much weight at the same time.

Also, what the actual laser body is made of is important to consider. If using a laser in combat its important that the shell of body of the laser is crafted with strong materials. Some of the world’s best lasers are made with strong aircraft grade aluminum or black polished brass which are both light and sturdy. The stronger the laser body the less chance that it can be damaged and malfunction.

Memory cards have replaced tapes and are fast replacing CDs and DVDs in music and video distribution industry as well.

The greatest advantage of all digital video cameras, apart from the higher quality of the camera lens etc., is of course the memory card. These cards have a capacity of anything up to 2GB’s. The cards can store videos of immense length, and once those have been transferred to a computer, they are back on the camera again, ready to roll for the next lot of videos. Most cameras come equipped with fairly small memory cards, and it is a standard procedure to purchase either one or two extra large capacity memory cards, depending on your storage requirements.

There are several formats of memory cards available. Each one of them is built for either one or two specific cameras, and you must check as to which one is compatible with your particular camera. The formats vary mainly on their speed and storage capacity. The quality of the image produced is generally similar in most video cameras, it is just the inbuilt compatibility requirements which differentiate each card. It is always recommended that you purchase a card which is compatible with more than one gadget, in order to avoid problems in the foreseeable future when you might want to upgrade or change your camera.
