in the 1960s, mexico began to develop the dn series of armored vehicles, which was a series of four-wheeled light armored vehicles. in terms of mexico's technical strength at the time, the performance of the dn series of armored vehicles could only be average, but it was enough to meet basic needs.

by the 1980s, this series of armored vehicles had developed into the dn-iv "horse", a 6.5-ton armored vehicle powered by a rear-mounted diesel engine. one of its two versions was equipped with a 20mm cannon. a single-man turret, and the other is equipped with a btr armored vehicle turret. the dn-v "bull" is a development version of the dn-iv. it appeared in 1984. it is already a relatively mature version, and based on it, the dn-v "buffalo" wheeled self-propelled howitzer was further developed.

the appearance of the dn-v "bull" armored vehicle is very similar to the american lav-150 armored vehicle. it is driven by a 184-horsepower cummins v-504 diesel engine and can reach a maximum speed of 80 kilometers, a maximum range of 500 kilometers, and a vehicle length of 5.89 meters, 3.06 meters wide, 2.5 meters high, with a crew of 4 and a combat weight of about 10.5 tons.

the dn-v "buffalo" self-propelled howitzer can only be regarded as a light fire support vehicle. it is made of the dn-v body and the turret of the m8 tracked self-propelled artillery developed by the united states during world war ii. technically speaking, it is not not complicated.

the m8 itself is developed from the m5 "stuart" light tank. it has an armored turret with an open top. the main weapon is a 75mm short-barreled howitzer, which can fire grenades, armor-piercing shells and smoke grenades. the maximum the range is 8.6 kilometers, and the auxiliary weapon is a 12.7mm machine gun mounted on the top. the role of the m8 is similar to that of armored weapons such as the no. 3 assault gun. it mainly provides real-time artillery support to the infantry and strikes targets such as firepower points. it played an important role during world war ii.

the production volume of dn-v "buffalo" is not large, and there is very little specific information about it. some articles say there are 5 units, and some say there are 6 units. anyway, the number is scarce. its role is to provide fire support just like the m8, but the "buffalo" is much lighter than the m8, its ability to withstand strikes is definitely much weaker, and its ammunition reserve may be smaller.

as a self-propelled howitzer in the 1980s, the dn-v "buffalo" is undoubtedly completely behind its contemporaries. its short-barreled 75mm howitzer originated from world war ii has worrying combat capabilities. most wheeled armored vehicles with enhanced firepower in the 1980s have the installation of long-barreled artillery, such as the french aml-90 4-wheeled armored vehicle, is very powerful. it is equipped with a long-barreled 90mm cannon weighing less than 6 tons, which can penetrate 320mm homogeneous when firing armor-piercing projectiles. steel armor, its strike capability far exceeds that of the "buffalo".

for the mexican army, they don’t seem to need powerful self-propelled howitzers. the country has only one military neighbor in the north that is too powerful to surpass. several other land and sea neighbors are not a threat, so naturally there is no need to think too much. to fight them, mexico's military is more often fighting drug traffickers.

the dn-v "buffalo" is also a good national defense parade equipment. after all, it is also mexico's "domestic equipment". some articles call it the first "mexican self-propelled howitzer."
