+unit_description= _ "Heavy infantry are a somewhat anomalous choice for outfitting troops. They are very difficult to send afield in war, and are useful mostly only in the defense of the city or castle in which they are stationed. Clad head to toe in full plate, and armed with large maces, heavy infantry excel at their sole purpose of melee combat. A few of them in the center of a line will shore up its strength considerably. The downsides to this are obvious, both in the weight of the metal, and the great care that must be taken of it, but in certain situations, these troops are well worth the trade-offs."

+unit_description= _ "Iron Maulers are given their name for reasons which are all too obvious. The men within these suits of armor can match ogres in contests of strength, and are marked as the champions of the castle guards in which they serve. They are, however, expensive to maintain, and cannot be sent to distant battles without a full convoy of servants to support them.

+Though staggering in melee combat, there are many drawbacks to being outfitted in this way; Iron Maulers tire easily, and know all too well that they cannot run on the battlefield. Too often have they seen a distant comrade fall, yet were powerless to reach the scene in time to help."

+unit_description= _ "Shock troopers are the elite of the heavy infantry, and half of their use in war is simply a matter of intimidation. The only men who can enter their ranks are prodigiously well-built, and when clad in black plate brimming with spikes, they are a fearsome sight to behold. The sight of Shock Troopers breaking an enemy with their morning stars is often enough to shatter the morale of any opposition, who sometimes wonder if such armor covers monsters, rather than men. The drawback of such heavy armor is, of course, the time it takes to move into and out of combat."
