Part of the richness of the Battletech universe is its inherent diversity. Each planet's population reflects the culture that settled it, the environment that molded it, the technology that defines day-to-day life, and lastly the empire that rules it. Too often, we fall into the trap of making every world "Lyran" or "Draconis" or "Periphery" without taking the time to make the planet a unique place to adventure.
This first article addresses the styles of military units that can be encountered across the Inner Sphere and Periphery (since most of us play military oriented games). The follow up articles will discuss such topics as government's types, religion, economics, etc. Note that in this article several topics will overlap, but each topic offers a new angle on the troops in question.
Regulars - House regulars are the most common troops in the Inner Sphere. This is for several reasons. The Great Houses have the existing training infrastructure, the resources to supply equipment, and a large number of willing and patriotic recruits. As such, regulars are usually the best-equipped, most standardized, best-trained, most professional, and well-rounded units. They are used to spearhead campaigns and assaults and to hold valuable worlds. Sometimes a unit will have been stationed on a world so long that they almost become a garrison force, with an attachment to that world in particular. Other units, particularly the more elite forces, have a high operations tempo and are sent to "hot spots" frequently and as needed.
Size: Armies
Type: Combined Arms
Quality: Good
Experience: Regular
Large - The Great Houses are not the only nobility to employ troops. Nobles ruling one or more worlds are also often responsible for providing soldiers to protect their holds and aid in campaigns across the empire. Considered personal troops, these "Guards" are often of high quality and experience, being drawn exclusively from the most populous and industrialized worlds. These units are nominally considered House Regulars and are listed as such, but in truth their loyalties are to their own liege first and foremost. There are several instances of nobles leading their own campaigns, with or without the permission of their ruling Successor State.
Size: Regiments
Type: Combined Arms
Quality: Excellent
Experience: Veteran
Small - Every noble house employs some form of bodyguards or security. These minor nobles can have units ranging from a squad of bodyguards for their estates to entire companies of armored vehicles and infantry. Often, a noble mechwarrior will still have his personal mech and maybe even a full lance.
Size: Squad to Company
Type: Conventional
Quality: Good
Experience: Regular
Large - Larger corporations often have a formidable security force. Military manufacturers tend to use the designs they produce to defend their holdings. These troops are usually ex-military and can be quite competent. Combine this with enough money to buy good equipment and you have a force the equal of a regular unit, if not as large.
Size: Companies
Type: Combined Arms
Quality: Good
Experience: Regular
Small - Smaller corporations are more concerned with industrial espionage and criminals than with planetary raids. Reflecting this concern, their forces are usually security guards with small arms or stun equipment. Although some guards may be ex-military, most are either former police or civilians. They tend to have effective surveillance systems and often work hand in hand with local authorities.
Size: Squads
Type: Infantry
Quality: Average
Experience: Green
Large - Larger militia units are usually found on strategically important worlds such as industrial or border planets. They are just below regular units, and in some cases (such as the Marik Militias and the Davion March Militias) almost indistinguishable. Recruiting extensively from the local planet or region, militias tend to be fierce defenders. Combined with extensive knowledge of their home terrain, it almost makes up for their poorer equipment and less extensive training. Although they sometimes field mech and aerospace forces, militias tend to use large numbers of conventional troops due to their more frequent role as defenders.
Size: Regiments
Type: Combined Arms
Quality: Average
Experience: Green
Small - Every planet has some form of garrison. The small militias are usually volunteers who meet together and train, although the amount of "training" varies from unit to unit. They often provide their own gear, and because of this, tend to be light infantry. If the planetary or city governments help out, they can sometimes augment their forces with vehicle support. Without the support of other units, however, small militias tend to be good for little other than deterring raiders and aiding in the event of natural disasters.
Size: Platoons to Battalions
