Balancing Al and Critical Thinking for the Military Leaders
of Tomorrow
Al is becoming increasingly embedded in daily life,
transforming the way we work, communicate, and make
decisions. From virtual assistants and personalized
recommendations to smart home devices and automated
customer service, Al streamlines everyday tasks and
enhances convenience. As Al continues to evolve, its role in our livelihoods will only expand, making it an essential
tool for productivity and innovation. Rather than resisting
this technology, we should embrace it. Al has the
potential to enhance and expand our knowledge, enabling
more informed decision-making.
For future military leaders, it is critical that education and
training prioritize independent thinking and decisive action
rather than an overreliance on Al-driven systems. Leaders
must develop the confidence to question Al outputs,
evaluate their accuracy, and consider multiple perspectives
before making informed decisions, rather than blindly
accepting computer-generated recommendations. Al
struggles in unpredictable, high-stakes environments
where training data is insufficient to cover every potential
contingency. Future conflicts will demand leaders who can
adapt in real time, assess emerging threats, and execute
decisions based on experience, judgment, and battlefield
awareness - not just what a computer system suggests. To
maintain a strategic edge and operational superiority,
military leaders must cultivate a disciplined decisionmaking process that integrates Al as a tool while ensuring
that human intuition, adaptability, and ethical reasoning
remain at the forefront of command decisions. Though the
possibilities of Al are vast and impressive, it is crucial to
remember that its role should not be replace, but to
complement human intelligence.
The rapid evolution of Al presents both a strategic
advantage and a formidable challenge in shaping the next
generation of military leaders. Al can enhance decisionmaking, optimize operations, and expand battlefield
awareness, yet it must remain a force multiplier not a
replacement for human intellect. The true test of future
leadership lies in striking the right balance: leveraging Al's
capabilities while preserving the independent thought,
adaptability, and critical reasoning essential for command
in today's volatile geopolitical environment. In an era
where peer adversaries are racing to develop their own Aldriven strategies, our leaders must be prepared to
out-think, not just out-tech, the competition. Al should
sharpen human cognition, not dull it - because the future of
warfare will be won by those who can command both
machine intelligence and the power of the human mind.

New Al System could prevent vessel collisions by
reducing dependence on ship Captain
Researchers at Texas A&M University have created an
intelligent Al system that can help prevent accidents and
collisions at sea. Named 'Ship Collision Avoidance of
Machine Learning and Radar Technology for Stationary
Entities and Avoidance', or SMART-SEA, the platform
works to decrease the dependence on ship captains.
The project team was led by Dr Mirjan Fürth, an assistant
professor of ocean engineering, who was awarded a
contract by the US Department of the Interior (DOI) and
the US Department of Energy (DOE) through the Ocean
Energy Safety Institute (OESI). It is not completely an
autonomous system, rather it provides 'a human-in-theloop', who gives real-time instructions based on maritime
traffic weather and other factors.
This makes navigation safer and easier for the crew,
transiting crucial or dangerous waterways by providing
additional information and instructions. Collisions between
vessels and accidents like ships hitting stationary
structures like rigs or lighthouses are becoming common,
and most are caused by human error. This Al system will
help eliminate that, stated the project team.
Massive vessels have a lot of forward momentum that
their shipping distances are measured in miles rather than
metres. They also turn very slowly, meaning that any
collision has to factor in this slow movement while also
adjusting for sensor time lags, ocean current impacts and
several other factors.
The Al system has been developed keeping all the abovementioned factors in mind and is extremely accurate. The
research team also said that the system combines raw
radar imaging data with machine learning, enabling it to
identify moving objects even in bad weather with limited
visibility.
The machine learning algorithm detects stationary objects
as well from a large distance. The system uses
computational fluid dynamics models and machine
learning, which have been previously trained on vessel
motions, the team added. The system does all of this
while complying with International Regulations for
Preventing Collisions at Sea (COLREGs).

relationship between the Al system and the ship Captain,
