=Artillery.=--Horse artillery consists of men mounted on horses or on the limbers of the guns. They are armed with 12-pounders, and manoeuvre with cavalry. Field artillery moves more slowly, the men being carried on guns and waggons. Garrison or siege artillery furnishes gunners and heavy guns of position drawn by horses, bullocks, and in India, elephants. There are now 28 Horse batteries, 151 Field batteries, and 10 of the Mountain division of garrison artillery. =Badge.=--An honorary distinction worn on the colours of a regiment. According to the Queen's Regulations, all regimental badges granted under special authority to different corps are to be strictly preserved. =Baggage.=--In a military sense, includes clothes, camp-equipage, and cooking apparatus of a regiment or army. The baggage of troops, if proceeding by sea, is divided into "light" and "heavy" baggage. =Balloon.=--Useful in warfare for purposes of reconnoitring, also in cases of a beleaguered city of keeping up communications with the outside world. The Prussians reconnoitred the French position before Metz, in 1870, by means of a balloon with telegraph attached, and thus the survey of the position of the French army was instantaneously conveyed to General Von Moltke. =Bandoliers.=--Belts of leather or canvas to hold small-arm cartridges, worn over the shoulder. =Base of Operations.=--In military language represents the original line on which an offensive army forms, whether it be the frontier of a country, river, or safe position, whence it takes the field to invade an enemy's country. The base of operations in case of retreat is always kept open to fall back upon. =Battalion=--An infantry unit. A British battalion is composed of 1010 of all ranks and one machine-gun. It is usually constituted thus: Lieutenant-colonel in command, majors 4, captains 5, lieutenants (first and second) 16. =Battery.=--Signifies, first, generally guns grouped and in position for action; second, the unit of an artillery command, as a battalion of infantry or a squadron of cavalry; thirdly, any work, permanent or temporary, considered as a position for a group of guns.
