The objective of this study is to determine whether the accumulation of dirt on a battle dress garment affects the emissivity of said garment in the thermal radiation spectrum (8-12 μm). This is researched for the purpose of identifying whether there is a need for military units to spend time and resources on keeping battle dresses clean to minimize their thermal signature.To accomplish said objective, two experiments were conducted with the Swedish uniformssystem 90 (battle dress system) to determine change in emissivity due to dirt accumulation in relation to clean garments. Dirty garments were borrowed from active service personnel provided they had been used daily and not washed for over 6 months. Emissivity was gauged with a thermal camera from FLIR Systems.While differences could be identified in unison with the hypothesis, can no conclusion be drawn due to the low statistical significance of the results. This is due to the small sample sizes in relation to the difference observed.
