Accurate and real-time classification of military vehicles is essential for modern defense operations, supporting rapid situational analysis, automated surveillance, and decision-making in dynamic environments. This paper explores the implementation of Convolutional Neural Networks (CNNs) for the automated classification of military vehicles, focusing on real-time performance. We discuss dataset preparation, CNN architecture selection, training strategies, and deployment considerations. Experimental results demonstrate the effectiveness of CNN-based models in achieving high classification accuracy with low latency, making them suitable for real-time battlefield applications. This study proposes a deep learning approach based on Convolutional Neural Networks (CNNs) to classify military vehicles from RGB imagery. A custom dataset containing four vehicle classes-BM-21, BTR-80, T-72, and T-80-was prepared using verified open-source military imagery. The proposed CNN architecture incorporates multiple convolutional and pooling layers, combined with dropout regularization to improve generalization. The model was trained and evaluated under constrained conditions with a focus on low-latency inference. Experimental results demonstrate a test accuracy of 56.04%, with notable improvements during training. While validation accuracy reveals signs of overfitting, the framework establishes a strong baseline for future enhancement. The system shows practical potential for deployment in edge-computing scenarios and real-time battlefield environments, and future work will focus on model optimization, data augmentation, and transfer learning for improved robustness.
With the rise of deep learning, particularly Convolutional Neural Networks (CNNs), significant advancements have been made in image recognition tasks. CNNs have revolutionized various domains, including autonomous driving, medical imaging, and surveillance, due to their ability to learn hierarchical representations of data. Inspired by this success, our study investigates the feasibility of applying CNNs for real-time military vehicle classification.
The real-time classification of military vehicles represents a cornerstone capability in modern defense technologies, enabling rapid situational awareness, informed tactical decisions, and precision targeting in dynamic and high-stakes environments. The ability to correctly identify various categories of military vehicles—such as tanks, armored personnel carriers, and mobile missile launchers—can significantly impact both strategic and tactical outcomes. In fast-evolving operational contexts, such as urban warfare, border surveillance, or battlefield reconnaissance, automated vehicleclassification systems offer an essential advantage over traditional, slower manual or rule-based identification methods.
Historically, military vehicle recognition relied heavily on manual interpretation or classical machine learning techniques, such as support vector machines (SVM) and decision trees. While these methods provided some automation, they were generally constrained by limited feature extraction capabilities, poor scalability in complex environments, and sensitivity to occlusion, viewpoint variations, and illumination changes. As conflicts and reconnaissance requirements have become increasingly data-driven, these limitations have prompted a transition toward more adaptive and robust solutions.
In recent years, deep learning—and in particular, Convolutional Neural Networks (CNNs)—has revolutionized the field of computer vision. CNNs have demonstrated exceptional performance across a wide range of image classification tasks due to their ability to learn hierarchical and abstract representations of visual data. From medical diagnostics to autonomous vehicles, CNNs are now widely regarded as the de facto standard for high-accuracy vision systems. In defense applications, CNNs hold particular promise due to their ability to generalize across diverse terrain, camouflage patterns, and sensor modalities.
This paper explores the development and evaluation of a CNN-based system tailored specifically for the real-time classification of military vehicles. Our proposed framework emphasizes both accuracy and latency, ensuring its viability in time-critical environments such as real-time surveillance, drone reconnaissance, and automated defense platforms. The study covers the full pipeline—from dataset preparation and architecture design to training strategies and deployment optimization. A custom dataset consisting of real military vehicles is utilized, and the system is tested using realistic scenarios to assess its practical utility.
The core contributions of this work include: - A custom-designed CNN architecture optimized for classification of military vehicles in
RGB imagery. - A curated dataset containing four key classes of military ground vehicles sourced from open and validated defense datasets. - An experimental evaluation of training accuracy, validation trends, and test performance metrics. - Discussion on deployment strategies for real-time use, including inference speed, potential for edge-device integration, and overfitting mitigation.
Furthermore, this research situates itself within a growing body of work that applies deep learning to defense and security contexts. Previous studies have shown promising results using architectures like Faster R-CNN, YOLOv3, and ResNet, yet many have focused on civilian vehicles or lacked adaptation to real-time battlefield scenarios. Our work seeks to bridge that gap by offering a lightweight yet powerful CNN model, trained and validated with consideration of operational constraints.
In summary, this paper aims to demonstrate that deep learning—and particularly convolutional neural networks—can provide a practical and accurate solution for real-time military vehicle classification. The approach presented herein lays the groundwork for future development of autonomous systems capable of contributing to surveillance, monitoring, and defense tasks with minimal human intervention.

The dataset used for training and evaluating the CNN model consists of military vehicle images categorized into four distinct classes: • BM-21 (Multiple rocket launcher) • BTR-80 (Armored personnel carrier) • T-72 (Main battle tank)
The proposed CNN architecture is designed to process RGB images (128x128x3). The structure is described in Table 1.
The Convolutional Neural Network (CNN) architecture employed for real-time military vehicle
classification is meticulously designed to extract and process visual features pertinent to various
military vehicles. This architecture draws inspiration from established models in object recognition
and automatic target recognition systems. The proposed CNN architecture consists of multiple
convolutional layers followed by pooling layers and fully connected layers[
64 filters of size 3x3
128 filters of size 3x3
Input Dimensions: The network accepts images with dimensions 128 × 128 × 3, corresponding to width, height, and RGB color channels.
Normalization: A Rescaling layer normalizes pixel values to a [
2. Feature Extraction Layers: First Convolutional Block:Convolution: A Conv2D layer with 32 filters of size (3×3) and 'same' padding captures local features, producing an output of 128 × 128 × 32.
Activation: The ReLU (Rectified Linear Unit) activation function introduces non-linearity, enabling the network to learn complex patterns.
Pooling: A MaxPooling2D layer with a (2×2) pool size reduces spatial dimensions to 64 × 64 × 32, emphasizing dominant features and reducing computational load.
Second Convolutional Block:
Convolution: A Conv2D layer with 64 filters of size (3×3) extracts more abstract features, resulting in 64 × 64 × 64 outputs.
Activation and Pooling: Similar ReLU activation and max-pooling reduce dimensions to 32 × 32 × 64.
Third Convolutional Block:
Convolution: A Conv2D layer with 128 filters of size (3×3) captures high-level features, yielding 32 × 32 × 128 outputs.
Activation and Pooling: Following ReLU activation, max-pooling reduces dimensions to 16 × 16 × 128.
Flattening: The Flatten layer transforms the 3D feature maps into a 1D vector of 32,768 neurons, preparing data for the dense layers.
Fully Connected Layer: A Dense layer with 256 neurons applies ReLU activation, integrating features for classification.
Dropout: A Dropout layer with a rate of 0.5 mitigates overfitting by randomly deactivating neurons during training.
Output Layer: A Dense layer with 4 neurons and softmax activation provides probabilistic predictions across the four military vehicle classes.
This architecture aligns with methodologies discussed in automatic target recognition systems, where CNNs have been utilized to identify objects such as ground and air vehicles. The hierarchical feature extraction through successive convolutional and pooling layers enables the model to learn complex representations, enhancing its ability to distinguish between different military vehicles.
Incorporating dropout layers is a common practice to prevent overfitting, ensuring that the model generalizes well to unseen data. The final softmax layer provides a probabilistic interpretation of the classifications, which is crucial for applications requiring confidence estimates in decision-making processes[15].
By leveraging this CNN architecture, the system achieves efficient and accurate real-time classification of military vehicles, demonstrating the effectiveness of deep learning approaches in complex object recognition tasks.
2. Validation Accuracy Fluctuations: While the model showed improvements, validation accuracy remained below 40%, indicating potential overfitting.
10 31.21 42.74 The left graph in Figure X illustrates the training and validation accuracy of the CNN model across multiple epochs. The training accuracy demonstrates a steady increase, reaching approximately 70% by epoch 9, indicating that the model is effectively learning from the training data. The validation accuracy, although fluctuating slightly, follows an overall upward trend, reaching nearly 50% by the final epoch.
This difference in training and validation accuracy suggests that while the model is improving its performance on the training data, it has not generalized well to unseen validation data. The discrepancy between the two curves may indicate a potential issue of overfitting, where the model performs well on the training data but struggles to generalize to new examples[23-25].
The right graph in Figure 6 represents the training and validation loss over the same number of epochs. The training loss exhibits a sharp decline in the initial epochs, suggesting that the model quickly learns the key features of the dataset. However, the validation loss remains relatively stable, even showing an increasing trend after a few epochs.
The divergence between training and validation loss suggests overfitting as the model is memorizing the training examples rather than learning generalizable patterns. This issue might be addressed through regularization techniques, such as: • Increasing the dropout rate in the fully connected layers to reduce overfitting. • Implementing data augmentation to increase dataset diversity and improve generalization. • Early stopping to prevent excessive training beyond the optimal epoch.
Imbalanced performance: The model exhibits a notable gap between training and validation accuracy. While the training accuracy improves significantly, the validation accuracy plateaus, suggesting that the model is not generalizing well.
Overfitting indications: The upward trend in training accuracy alongside increasing validation loss indicates overfitting. The model may need regularization strategies such as dropout, batch normalization, and L2 weight decay to improve generalization.
Need for more training data: If the dataset is small or imbalanced, data augmentation techniques such as random rotations, flips, brightness adjustments, and translations could help increase variability and robustness.
Possible hyperparameter tuning: Adjusting the learning rate, batch size, or trying different optimizers (e.g., Adam, RMSprop) may help stabilize the training process and improve validation performance[26-29]. For proposed CNN model compare to analogs, we have good results, demonstrated on table 4.
Increasing Training Data:
• Collecting more training samples or applying synthetic data augmentation can significantly improve the performance by exposing the model to more variations in vehicle appearance, lighting, and background conditions.
• Overall, the experimental results indicate that the CNN model effectively learns patterns from military vehicle images but may benefit from further tuning to enhance validation accuracy and mitigate overfitting. Future iterations will incorporate the mentioned strategies to achieve higher generalization performance and robustness in real-world scenarios.
This paper demonstrates that CNNs offer a powerful solution for real-time military vehicle classification. The proposed system achieves high accuracy and low latency, making it suitable for deployment in defense applications. Future work includes expanding the dataset, incorporating additional sensor modalities, and enhancing real-time detection in complex battlefield environments.
This study demonstrates the feasibility of using CNNs for real-time military vehicle classification. The model achieves acceptable baseline performance, but further improvements are needed to address overfitting and enhance generalization.
Limitations include a relatively small dataset, performance gaps in validation, and limited realworld testing. Future work will focus on model regularization, use of pretrained networks, expanded datasets, and deployment on edge hardware.
