Electronic shot counters provide armorers with accurate tracking and allow more efficient preventive maintenance practices. We propose a machine learning technique for general-purpose ammunition type discrimination, thereby enhancing targeted maintenance. Design/methodology/approach–We study an experimental shot counter deployment to understand its impact on maintenance practices. We then extend the existing EDGAR machine learning technique to solve the discrimination problem in a generic way on a weakly-labelled dataset, requiring only the total counts for each shot type. By repurposing intermediate neural network activations, we simplify training and minimize computational overhead. We evaluate our approach against a widely used live/blank discrimination algorithm. Findings–We show a 94% improvement in instance-level error rate and perfect burst-firing performance. This generalizes across weapon platforms without hyperparameter adjustment. The feature incurs as little as an 8% overhead (2.8 ms on a 64 MHz ARM Cortex-M4F) .  \nOriginality/value – Compared to existing techniques, it promises applicability to a broader range of weapon configuration discrimination tasks, including platforms previously deemed too complex or constrained. Additionally, we examine how performance scales with dataset size to offer practical data collection guidelines, a major challenge in this field. This technique supports a new generation of shot counters and targeted maintenance, thereby reducing costs, preventing incidents and increasing operational availability.  \nKeywords Electronic shot counters, Gunshot detection, Ammunition discrimination, Preventive maintenance, Operational availability, Weakly supervised learning  \nPaper type Research paper  \n1. Introduction  \nThe acquisition and ongoing maintenance of small arms, along with the procurement of spare parts and accessories, represent substantial investments for modern armies. The management and upkeep of this weapon fleet demands considerable time and directly impacts the reliability of weapons, a factor critical to mission success and the safety of the user. Paradoxically, small arms management is one of the rare areas of military logistics that has not yet entered the digital era. Current tracking relies on manual paper logs and spreadsheets, leading to frequent errors that compromise maintenance schedules.  \nOne solution to this problem is the systematic use of electronic shot counters. These devices continuously and accurately track weapon usage and maintenance status.  \n© Nathan Morsa. Published in the Journal of Defense Analytics and Logistics.
