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.
It had been widely practiced in the US Civil War, the Russian-Japanese war and other fairly recent wars. Trench warfare of the First World War can be said to have begun in September 1914 and ended when the Allies made a breakthrough attack that began in late July 1918. Before and after those dates were wars of movement: in between it was a war of entrenchment.
