conscription does not exist
Conscription has never existed.
The introduction of conscription is not foreseen. However it was announced in 1990 that all university students had to undergo military training if they wished to graduate. Introduced as a reaction to the Iraqi invasion of Kuwait, the authorities decided to regard this requirement as a possible prelude to reservist training. No further details are known. 
The United Arab Emirates is a federation of seven separate emirates that united in 1971-72 to form a single independent country. Before 1971 the United Kingdom was responsible for the defence of these countries. The armed forces, the Union Defence Forces (UDF) are a combination of the separate emirate forces, the Abu Dhabi forces being the most dominant. Separate emirate forces do still exist but are called regional commands of the UDF. Military expenditure constitutes 40 percent of government spending - one of the highest percentages of all countries in the world. 
As in the other Persian Gulf States, the armed forces are to a large extent composed of foreign volunteers: at least 30 percent of army rank-and-file are foreigners.
