@Skitters - Those are exactly what I was looking for, thanks!!!
cool...I'll keep plugging away at some more then. Note I won't take offence if you feel any are not quite what you're after, or if you see any obvious refinements you want to make to them.
Also noticed there was a couple of typo's in the early fighter text, which I've now corrected.
Here is the next batch. Hopefully I'll get a chance to do some more later....but guess I really should do some work!
-Intermediate Fighter (Example: Albatros D.III, Sopwith Pup, Nieuport 11, etc)
Better engine developments, and design, a move to more stable biplanes, plus further refinement of synchronization gear and a move to duel machine guns saw fighters improve further as the war progressed. As fighters had been developed to respond to early reconnaissance aircraft and bombers, there now became a development race to give fighter pilots an advantage in speed, maneuverability and hitting power as the skies became increasingly busier with dogfights.
-Late Fighter (Example: SPAD XIII, Sopwith Camel, Fokker D.VII, etc)
Further aerodynamic improvements, the refinement of cantilever wings and more powerful engines saw fighters reach new levels of performance. Frontline fighter pilots were increasingly asked for advice and to help evaluate the latest developments. Strengthened structures improved endurance as pilots put their airframes under increasing pressures as they dueled in the skies.
-Medium Bomber (Example: AEG G.IV, DH.4, Breguet Br14, etc)
As the war progressed, the size of bombers also grew as each side looked to maximise the damage it could inflict on the other. Whilst they would still perform a reconnaissance role, the planes were now developing a more distinct role as Bombers. Larger sections of airframe were now being made from metal, making them lighter but also able to withstand more damage. Coupled with larger engines, payloads increased as the crew looked to reap devastation on the enemy forces below.
-Heavy Bomber (Example: Handley Page O/100, Ilya Muromets, Gotha G.IV, etc)
As early as December 1914 during the First World War the Royal Navy's Director of the Air Department, Captain Murray Sueter requested "a bloody paralyser" of an aircraft from Frederick Handley Page for long-range bombing. Large wingspans, multiple engines, meant heavier payloads could be carried in order to carry out strategic air raids on ports, railway targets and airfields with payloads of upto 800kg of bombs. Longer range also allowed these craft to perform an anti-submarine role. Multiple gun points and armor plating afforded some protection from fighters planes.
-Armored Car (Example: Rolls Royce, Ehrardt, Charron, etc)
First seen in the Italo-Turkish war of 1912, the armed forces were quick to see the potential of fast, armored vehicles. Primarily armed with light machine guns, they provided a fast, mobile weapons platform. Their good speed and range made them useful for a reconnaissance role, and as the air war developed they also fulfilled a mobile anti-aircraft role. They had a key role in the Race to the Sea and rescuing downed fighter pilots, but as the Western front ground to a halt it became apparent that they had only limited use in muddy trenches. They were, however, able to operate in other theaters such as the Near East.
Awesome work with units, and techs and everything.... That mod is already a jewel. When it'll be completed it'll be definitly one of the best mod!
I add this effect to all .dds in game - I've made all .dds from Terrain folder, Half of the Interface folder - You should see now buttons - they look very old
