You can have a private early pregnancy scan any time from 6 weeks onwards as we should see a heartbeat although, at this stage it is very small approximately 5mm. These dates are calculated from the first day of your last menstrual period LMP , not the day of conception. Before 5 weeks it is not possible to see any signs of a pregnancy with current ultrasound technology. Waiting a few weeks will allow you to see more, and if all looks good at 8 weeks you will be reassured to know the chance of miscarriage is very low.
If you are unsure of dates or have an irregular menstrual cycle you may wish to wait 2 weeks from a positive pregnancy test to be sure of seeing signs of a pregnancy.
Sometimes the results of a first trimester scan may be inconclusive or uncertain, and need to be combined with your clinical history and blood tests (serum BhCG). Some women need to return for another ultrasound scan a few weeks later to assess the progress of the pregnancy, or they may require another blood test (serial serum BhCG).
First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.
Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby. Transabdominal ultrasound involves scanning through your lower abdomen. A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.
The gel helps improve contact between the probe and your skin. Transvaginal ultrasound is an internal ultrasound. It involves scanning with the ultrasound probe lying in the vagina. Transvaginal ultrasound usually produces better and clearer images of the female pelvic organs including the developing pregnancy, because the ultrasound probe lies closer to these structures. The transvaginal ultrasound probe is thin, about 2cm diameter.
The probe is covered with a disposable protective sheath.

See Article History Military communication, the transmission of information from reconnaissance and other units in contact with the enemy and the means for exercising command by the transmission of orders and instructions of commanders to their subordinates. As such, it comprises all means of transmitting messages, orders, and reports, both in the field and at sea and between headquarters and distant installations or ships.
Military communication has thus long played an important role in warfare. Early development Messengers have been employed in war since ancient times and still constitute a valuable means of communication. Alexander, Hannibal, and Caesar each developed an elaborate system of relays by which messages were carried from one messenger post to another by mounted messengers traveling at top speed.
They were thus able to maintain contact with their homelands during their far-flung campaigns and to transmit messages with surprising speed. Genghis Khan at the close of the 12th century not only emulated his military predecessors by establishing an extensive system of messenger posts from Europe to his Mongol capital but also utilized homing pigeons as messengers.
