RISK
1-36. Choices and the cost of those choices characterize all operations. Commanders decide if they can
accomplish their mission based on current intelligence of the enemy situation and an assessment of the assets
available (including time) and the means to coordinate and synchronize those assets. If those assets are not
available, commanders choose to take additional time to plan, resource, and prepare for an operation, or they
articulate where and how they will assume risk.
1-37. Commanders may act on limited combat information in a time-constrained environment. Combat
information is unevaluated data, gathered by or provided directly to the tactical commander which, due to its
highly perishable nature or the criticality of the situation, cannot be processed into tactical intelligence in
time to satisfy the user’s tactical intelligence requirements (JP 2-01). Commanders must understand the
inherent risk of acting only on combat information, since it is vulnerable to enemy deception and can be
misinterpreted. The intelligence staff helps commanders assess combat information used in decision making.
1-38. Commanders cannot be successful without a willingness to act under conditions of uncertainty, which
demands balancing risks with taking advantage of opportunities. No amount of intelligence can eliminate all
uncertainties and inherent risks of tactical operations. Commanders will never have absolute situational
understanding. A lack of information must not paralyze the decision-making process. The more information
a commander collects concerning the mission variables, the better that commander is able to make informed
decisions. Less information means that a commander has a greater risk of making a poor decision for a
specific situation. Knowing when there is enough information to make a decision within the higher
commander’s intent and constraints is part of the art of tactics and is a critical skill for all leaders.
1-39. To shape success, commanders take the minimum time necessary to plan and prepare. Reduced
coordination at the start of an operation may result in less than optimal effects on the enemy. However, that
reduced coordination may offer increased speed and momentum and, potentially, surprise. The more time a
commander takes to prepare for an operation, the more opportunity the enemy has to prepare.
1-40. Bold decisions that are adequately informed give the best promise of success. Commanders accept risk
when making decisions because there will always be a degree of uncertainty. Opportunities come with risks.
The willingness to accept risk is often the key to exposing enemy weaknesses. There are times when leaders
cannot find ways of addressing all of the risk and should consider if the outcome is worth the risk. Situational
understanding, running estimates, and planning reduces risk.
1-41. In some circumstances, commanders can forego detailed planning, extensive rehearsals, and significant
changes in task organization. Their prior self-development, training, and experience allows them to assess
and create overwhelming combat power at decisive points. For example, an attacking battalion task force
encountering enemy security elements just moving into position can conduct actions on contact to destroy
these elements without the loss of momentum. Actions on contact are a series of combat actions, often
conducted nearly simultaneously, taken on contact with the enemy to develop the situation. Friendly
commanders determine what must be done to preserve combat power and create conditions for success.
1-42. Every military decision includes risk. Commanders exercise judgement when deciding where to accept
risk. As shown in figure 1-1, commanders have several techniques available to reduce the risk associated
with a lack of information and intelligence in a specific operation. Some of these techniques for reducing risk
require the commitment of additional resources. Deciding what resources to divert to reduce risk is part of
the art of tactics. In general terms, risk is the exposure of someone or something valued to danger, harm, or
loss. Risk is an expression of the probability and implications of an activity or event, with positive or negative
consequences taking place. It is a measure of the likelihood of something going right or wrong, and the
associated impact, good or bad.
1-43. Because risk is part of every operation, it cannot be avoided. Commanders analyze risk in collaboration
with subordinates to help determine what level of risk exists and how to mitigate it. When considering how
much risk to accept with a COA, commanders consider risk to the force and risk to the mission against the
perceived benefit. They apply judgment with regard to the importance of an objective, time available, and
anticipated cost. Commanders need to balance the tension between creating opportunities, protecting the
force, and accepting and managing risks that must be taken to accomplish their mission.
