Tutorial 6: CONTRACTS VS GRANTS. The eleven agencies that participate in the SBIR and STTR programs make their awards either as grants or contracts. In 2015 the combined SBIR and STTR budget across all of the participating agencies was $2.5 billion dollars. Of that a little over half was provided to small businesses in the form of contracts; while the other half was provided as grants.
Trench warfare is a type of land warfare using occupied fighting lines consisting largely of trenches, in which troops are significantly protected from the enemy's small arms fire and are substantially sheltered from artillery. The most famous use of trench warfare is the Western Front in World War I.
Trench warfare was not an innovation of World War I, but it was never so prevalent in any other war before or since. One reason that World War I became a massive trench war on the Western Front was that western Europe was densely populated. The opposing armies in the west were so vast that they could be deployed across the entire European continent, forming a continuous front.
